You use the same graph as for training the network, but instead of optimizing w.r.t. the parameters of the network, you optimize w.r.t the input (which has to be a variable with the shape of your input image). Your optimization target is the negative (because you want to maximize, but TF optimizers minimize) logit of your target class. You want to run it with a couple of different initial values for the image.
There's also a few related techniques, if you search for DeepDream and adversarial examples you should find a lot of literature. | 1 | 1 | 1 | In TensorFlow it is pretty straight forward to visualize filters and activation layers given a single input.
But I'm more interested in the opposite way: feeding a class (as one-hot vector) to the output layer and see something like the optimal input image for that specific class.
Is there a way to do so or to run the graph reversed?
Background: I'm using Googles Inception V3 with 15 classes and I've trained the network already with a large amount of data up to a good precision.

It seems to be a limitation in how the LocalExecutor works. The scheduler ends up spawning child processes (32 in your case). In addition, your scheduler performs 20 iterations per execution, so by the time it gets to the end of its 20 runs, it waits for its child processes to terminate before the scheduler can exit. If there is a long-running child process, the scheduler will be blocked on its execution.
For us, the resolution was to switch to the CeleryExecutor. Of course, this requires a bit more infrastructure, management, and overall complexity for the Celery backend. | 1 | 2 | 0 | I am using airflow 1.7.1.3.
I have an issue with concurrency DAGs / Tasks. When a DAG is running, the scheduler does not launch other DAGs any more. It seems that scheduler is totally frozen (no logs anymore) ... until the running DAG is finished. Then, the new DAGrun is triggered. My different tasks are long-running ECS task (~10 minutes)
I used LocalExecutor and I let default config about parallelism=32 and dag_concurrency=16. I use airflow scheduler -n 20 and reboot it automatically and I set 'depends_on_past': False for all my DAGs declaration.
For information, I deployed airflow in containers running in an ECS cluster. max_threads = 2 and I have only 2 CPU available.

My shapefile is always static, only the attributes of the features will change. So I copy my original shapefile (only the basic files with endings .shp, .shx, .prj) to my output folder and rename it to the name I want.
Then I create my CSV-File with all calculations and convert it to DBF and save it with the name of my new shapefile to the output folder too. ArcGIS will now load the shapefile along with my own DBF file and I don't even need to do any tablejoin at all!
Now my program runs through in only 50 seconds!
I am still interested in more solutions for the table join problem, maybe I will encounter that problem again in the future where the shapefile is NOT always static. I did not really understand Nan's solution, I am still at "advanced beginner" level in Python :)
Cheers | 1 | 2 | 1 | I have created a rather large CSV file (63000 rows and around 40 columns) and I want to join it with an ESRI Shapefile.
I have used ArcPy but the whole process takes 30! minutes. If I make the join with the original (small) CSV file, join it with the Shapefile and then make my calculations with ArcPy and continously add new fields and calculate the stuff it takes 20 minutes. I am looking for a faster solution and found there are other Python modules such as PySHP or DBFPy but I have not found any way for joining tables, hoping that could go faster.
My goal is already to get away from ArcPy as much as I can and preferable only use Python, so preferably no PostgreSQL and alikes either.
Does anybody have a solution for that? Thanks a lot! | DBF Table Join without using Arcpy? | 0 | 1 | 0 | 377 |

Hope this helps! | 1 | 3 | 0 | I have a repeatable problem with my laptop (an HP G4 250 that came with windows 10). I can be happily on the Internet, but opening Spyder causes the Internet to immediately die. Now, the system does something rather unusual. I am not disconnected from the router, and the wireless icon still says I am connected and have Internet access. But streams crash, webpages refuse to load and say there is no internet connection, and I can;t even access my router's config page.
Closing Spyder fixes the problem. Not instantly, but when Spyder is open, it creates several pythonw.exe network requests (seen from resource manager) and the Internet is restored when those processes close themselves upon exiting Spyder (typically 10 seconds to 2 minutes, depending on system load).
I have added Spyder to my firewall, but that has done nothing. I haven't added (nor found) pythonw.exe, but it's not Spyder that has the problem with connecting, it's my entire machine.
It's not coincidental. It's happened now, 2 days in a row, and is highly repeatable. After a while with Spyder being open, I can sometimes receive intermittent Internet function, but it frequently drops until I close the program.
After experiencing it last night, I purged my driver and reinstalled it fresh, and that has fixed nothing. I am running the latest wireless driver provided by HP for my machine. As this problem only occurs when running Spyder, I doubt it's a driver or hardware issue.

We get a warning on Django 1.9, which will become an error on Django 1.10. This is blocking our upgrade, and I want to contribute a fix to the app so we can upgrade.
One option would be to modify the requirements in setup.py so that Django 1.10 is required. But I'm sure my contribution would be rejected since it would break for everyone else.
To maintain backwards compatibility, I can do the import as a try/except but that feels hacky. It seems like I need to do some Django version checking in the imports. Should I do a Django version check, which returns a string, convert that to a float, and do an if version > x? That feels hacky too.

When you have a statically typed language background (Java in my case), it's a bit unusual. Dynamic typing saves you a lot of time and lines of code in large scripts. It prevents you from having errors because you have forgotten to define some variable. However, static typing lets you have more control on how data is stored in a computer's memory. | 2 | 3 | 0 | In Python, if you want to define a variable, you don't have to specify the type of it, unlike other languages such as C and Java.

As a result python interpreter will distinguish the variable's types (in running time) and give the exact space in memory needed. Despite being dynamically typed, Python is strongly typed, forbidding operations that are not well-defined (for example, adding a number to a string) .
On the other hand C and C++ are statically typed languages which means that the types of variables are known in compilation time.
Using dynamic typing in programming languages has the advantage that gives more potential to language, for example we can have lists with different types (for example a list that contains chars and integers). This wouldn't be possible with static typing since the type of the list should be known from the compilation time...).
One disadvantage of dynamic typing is that the compiler-interpreter in many cases must keeps a record of types in order to extract the types of variables, which makes it more slow in comparison with C or C++.
A dynamic typed language like python can be also strongly typed. Python is strongly typed as the interpreter keeps track of all variables types and is restrictive about how types can be intermingled. | 2 | 3 | 0 | In Python, if you want to define a variable, you don't have to specify the type of it, unlike other languages such as C and Java.

There are some amazing guys here, but you might want to take it to one of the FileMAker forums as the FIleMAker audience there is much larger then in SO | 1 | 0 | 0 | This is quite a general question, though I’ll give the specific use case for context.
I'm using a FileMaker Pro database to record personal bird observations. For each bird on the national list, I have extracted quite a lot of base data by website scraping in Python, for example conservation status, geographical range, scientific name and so on. In day-to-day use of the database, this base data remains fixed and unchanging. However, once a year or so I will want to re-scrape the base data to pick up the most recent published information on status, range, and even changes in scientific name (that happens).
I know there are options such as PyFilemaker or bBox which should allow me to write to the FileMaker database from Python, so the update mechanism itself shouldn't be a problem.
It would be rather dangerous simply to overwrite all of last year’s base data with the newly scraped data, and I'm looking for general advice as to how best to provide visibility for the changes before manually importing them. What I have in mind is to use pandas to generate a spreadsheet using the base data, and to highlight the changed cells. Does that sound a sensible way of doing it? I suspect that this may be a very standard requirement, and if anybody could help out with comments on an approach which is straightforward to implement in Python that would be most helpful. | Providing visibility of periodic changes to a database | 1.2 | 1 | 0 | 46 |

So far I've tried different approaches:
I tried different keypoint extraction and description algorithms: SIFT, SURF, ORB. SIFT and SURF are too heavy and ORB is not so good.
Then I tried using different algorithms for keypoint extraction and then description. The first approach was to use FAST algorithm to extract key points and then ORB or SURF for description, the results were not good and not rotation invariant, then i tried mixing the others.
I now am to the point where I get the best results time permitting using ORB for keypoint extraction and SURF for description. But it is still really slow.

Often, the user level configuration of an application is placed under your home folder as a dot file. So what you can do is like this:
In your git repository, track a sample configure file, e.g., config.sample.yaml, and put the configuration structure here.
When deploying, either in test environment or production environment, you can copy and rename this file as a dot-file, e.g., $HOME/.{app}.config.yaml. Then in your application, you can read this file.
If you are developing an python package, you can make the file copy operation done in the setup.py. There are some advantages:
You can always track the structure changes of your configuration file.

You can get and set such attributes via getattr and setattr, but they can't be accessed with ordinary dot syntax (something like obj.class is a syntax error), so they're a pain to use.
As Aurora0001 mentioned in a comment, a convention if you "need" to use them is to append an underscore. The most common reason to "need" to have such attributes is that they're generated programatically from an external data source.

I want to incorporate collaborative filtering approach, its user-user variant.

When we have new user who liked couple of things we just find users who liked same items and recommend to this new user items which were liked by users similar to new user.
But I want to add some twist to it. I will be recommending places to users, namely 'where to go tonight'.

Attempts:
plt.imshow(X) results in a tall, skinny graph because of the shape of X. Using plt.imshow(X, aspect='auto) will stretch out the graph horizontally, but the dots get stretched out to become ellipses, and the plot becomes hard to read.
ax.spy suffers from the same problem.
bokeh seems promising, but really taxes my jupyter kernel.
Bonus:
The nonzero entries of X are positive real numbers. If there was some way to reflect their magnitude, that would be great as well (e.g. colour intensity, transparency, or across a colour bar).
Every 500 rows of X belong to the same class. That's 12 classes * 500 observations (rows) per class = 6000 rows. E.g. X[:500] are from class A, X[500:1000] are from class B, etc. Would be nice to colour-code the dots by class.

plt.imshow(X) results in a tall, skinny graph because of the shape of X. Using plt.imshow(X, aspect='auto) will stretch out the graph horizontally, but the dots get stretched out to become ellipses, and the plot becomes hard to read.
ax.spy suffers from the same problem.
bokeh seems promising, but really taxes my jupyter kernel.
Bonus:
The nonzero entries of X are positive real numbers. If there was some way to reflect their magnitude, that would be great as well (e.g. colour intensity, transparency, or across a colour bar).
Every 500 rows of X belong to the same class. That's 12 classes * 500 observations (rows) per class = 6000 rows. E.g. X[:500] are from class A, X[500:1000] are from class B, etc. Would be nice to colour-code the dots by class. For the moment I'll settle for manually including horizontal lines every 500 rows to delineate between classes. | Python: Plot a sparse matrix | 0 | 0 | 0 | 2,877 |

I guess this might stop the ArcMap version of python working properly but since I'm not using python with ArcMap at the moment it's not a big problem. | 1 | 0 | 1 | I recently installed ArcGIS10.4 and now when I run python 2.7 programs using Idle (for purposes unrelated to ArcGIS) it uses the version of python attached to ArcGIS.
One of the programs I wrote needs an updated version of the pandas module. When I try to update the pandas module in this verion of python (by opening command prompt as an administrator, moving to C:\Python27\ArcGIS10.4\Scripts and using the command pip install --upgrade pandas) the files download ok but there is an access error message when PIP tries to upgrade. I have tried restarting the computer in case something was open. The error message is quite long and I can't cut and paste from command prompt but it finishes with
" Permission denied: 'C:\Python27\ArcGIS10.4\Lib\site-packages\numpy\core\multiarray.pyd' "
I've tried the command to reinstall pandas completely which also gave an error message. I've tried installing miniconda in the hope that I could get a second version of python working and then use that version instead of the version attached to ArcMap. However I don't know how to direct Idle to choose the newly installed version.
So overall I don't mind having 2 versions of python if someone could tell me how to choose which one runs or if there's some way to update the ArcMap version that would be even better. I don't really want to uninstall ArcMap at the moment.
Any help is appreciated! Thanks! | How to update pandas when python is installed as part of ArcGIS10.4, or another solution | 0 | 0 | 0 | 212 |

You can use IDLE interactively, like in Terminal (a.k.a command line), or use it to write your script rather than in a separate text editor. Then once you save your script/program you can do neat things like run it directly from IDLE. There's nothing more special about the Terminal, you just have to do some more work.
Furthermore, all the code you have written on your GUI is on the cache memory which is used in system to store information recently accessed by a processor. So, I suggest you write again your code you can't recover them without saving.
To avoid these kind of problems use Git!

One can edit any line of a statement before submitting it for execution. After executing, one may recall any statement by either a) placing the cursor anywhere on the statement and hitting Enter, or b) using the history-next and history-prev actions. On Windows, these are bound, by default, to Alt-p and Alt-p. To check on your installation, Select Options => IDLE preferences on the menu. In the dialog, select the Keys tab. Under Custom Key Bindings, find the 'histor-xyz' actions in the alphabetical list.
For short, one-off scripts, I have a scratch file called tem.py. Since I use it often, it is usually accessible via File => Recent files. | 3 | 1 | 0 | When reading a book or just coding on terminal/IDLE it's common to make typo, forgot brace or comma etc. After I got error and all what I wrote before is lost.
