Here it goes:
1) Prepare TF-IDF matrix: Represent documents in terms Term Vectors. Why not LDA because you need to supply number of themes first which you don't know first. You can use other methods of representing documents if want to be more sophisticated (better than semantics) try word2Vec, GloVe, Google News Vectors etc.
2) Prepare a Latent Semantic Space from the above TF-IDF. Creation of LSA uses SVD approach (one can choose the kaiser criteria to choose the number of dimensions).
Why we do 2)?
a) TF-IDF is very sparse. Step 3 (tSne) which is computationally expensive.
b) This LSA can be used to create a semantic search engine
You can bypass 2) when your TF-IDF size is very small but i don't think given your situation that would be the case and also, you don't have other needs like having semantic search on these documents.
3) Use tSne (t-stochastic nearest embedding) to represent the documents in 3 dimensions. Prepare a spherical plot from the euclidean cordinates.
4) Apply K-means iteratively to find the optimal number of clusters.
Once decided. Prepare word clouds for each categories. Have your themes. | 1 | 0 | 1 | I am trying to do textual analysis on a bunch (about 140 ) of textual documents. Each document, after preprocessing and removing unnecessary words and stopwords, has about 7000 sentences (as determined by nlkt's sentence tokenizer) and each sentence has about 17 words on average. My job is to find hidden themes in those documents.
I have thought about doing topic modeling. However, I cannot decide if the data I have is enough to obtain meaningful results via LDA or is there anything else that I can do.
Also, how do I divide the texts into different documents? Is 140 documents (each with roughly 7000 x 17 words) enough ? or should I consider each sentence as a document. But then each document will have only 17 words on average; much like tweets.
Any suggestions would be helpful.

So upcoming event would be placed on SQS, and then other lambda would be used to do processing. Problem is that time of processing is limited to 5 min. Also delivering can't be parallel.
Other option is to have one input queue, and one output queue per receiver. So the lambda function, which process input, just spreads it through other queues. And then other lambdas are responsible for delivering. That way has other obvious problems.
Finally. Your lambda, while processing input, can generate messages on outgoing queue, instrumenting what message should be delivered to which users. Then you can have one lambda triggered on each message from outgoing queue. And there you can have small loop delivering messages. Note that in case of problems you need to send back what was not delivered.
Good point is that SQS has something like dead letter queue, so that problematic messages would not stay there forever. | 1 | 0 | 0 | I'm implementing a webhooks provider and trying to solve some problems while minimizing the added complexity to my system:

This is not a trivial operation that you are attempting. In order to understand why, you must understand what these word vectors are.
Word embeddings are vectors that attempt to encode information about what a word means, how it can be used, and more. What makes them interesting is that they manage to store all of this information as a collection of floating point numbers, which is nice for interacting with models that process words. Rather than pass a word to a model by itself, without any indication of what it means, how to use it, etc, we can pass the model a word vector with the intention of providing extra information about how natural language works.
As I hope I have made clear, word embeddings are pretty neat. Constructing them is an area of active research, though there are a couple of ways to do it that produce interesting results. It's not incredibly important to this question to understand all of the different ways, though I suggest you check them out. Instead, what you really need to know is that each of the values in the 300 dimensional vector associated with a word were "optimized" in some sense to capture a different aspect of the meaning and use of that word. Put another way, each of the 300 values corresponds to some abstract feature of the word. Removing any combination of these values at random will yield a vector that may be lacking significant information about the word, and may no longer serve as a good representation of that word.
So, picking the top 100 values of the vector is no good. We need a more principled way to reduce the dimensionality. What you really want is to sample a subset of these values such that as much information as possible about the word is retained in the resulting vector. This is where a dimensionality reduction technique like Principle Component Analysis (PCA) or t-distributed Stochastic Neighbor Embeddings (t-SNE) come into play. I won't describe in detail how these methods work, but essentially they aim to capture the essence of a collection of information while reducing the size of the vector describing said information. As an example, PCA does this by constructing a new vector from the old one, where the entries in the new vector correspond to combinations of the main "components" of the old vector, i.e those components which account for most of the variety in the old data.
To summarize, you should run a dimensionality reduction algorithm like PCA or t-SNE on your word vectors. There are a number of python libraries that implement both (e.g scipy has a PCA algorithm). Be warned, however, that the dimensionality of these word vectors is already relatively low. To see how this is true, consider the task of naively representing a word via its one-hot encoding (a one at one spot and zeros everywhere else). If your vocabulary size is as big as the google word2vec model, then each word is suddenly associated with a vector containing hundreds of thousands of entries! As you can see, the dimensionality has already been reduced significantly to 300, and any reduction that makes the vectors significantly smaller is likely to lose a good deal of information. | 1 | 2 | 1 | I loaded google's news vector -300 dataset. Each word is represented with a 300 point vector. I want to use this in my neural network for classification. But 300 for one word seems to be too big.

a table would work as well, since you haven't stated that x and y geometries have any numeric purpose other than as lablels. | 1 | 0 | 1 | I have a set of about 2000 files that look like: 10_20.txt, 10_21.txt, 10_21.txt, ... ,10_50.txt, ... , 11.20.txt, ... , 11.50.txt , ... , 20_50.txt
The first value in the file name, we'll call x, goes from 10-20 in steps of 1, and the second value in the file name, we'll call y, and goes from 20-50 in steps of 1.
Within these files, there is a load of values and another value I want to extract, which we'll call z.
I have written a program to cycle through the files and extract z from each file and add it to a list.
My question now is, if I have 2 numpy arrays that look like:
x = np.arange(10,20,1)
y = np.arange(20,50,1)
and a z list that has ~2000 floats in it, what is the best way to plot how z depends on x and y? Is there standard way to do this?
I had been thinking it would be best to extract x, y and z from a file, and add them to a multidimensional array. If this is the case could anyone point me in the right direction of how to extract the x and y values out of the file name. | Plotting a 3d surface in Python from known values | 0 | 0 | 0 | 470 |

A lot of the numbers generated have pretty high precision floating points, so:

I want to figure out the best way, either in Python with MySQL(MariaDB) - to store the number with smallest data size.
So 2.132e-7 or 3.232e5, just to basically store it as with as little footprint as possible, with a decimal range that I can specify - but removing the information after n decimals.
I assume storing as a DOUBLE is the way to go, but can I truncate the precision and save on space too?
I'm thinking some number formating / truncating in Python followed by just normal storage as a DOUBLE would work - but would that actually save any space as opposed to just immediately storing the double with N decimals attached.

The Windows command prompt defaults to your environmental settings unless you tell it explicitly the path of the pip/python you want - which will always be in the Scripts folder of your virtualenv.
So for instance, to use the virtualenv version of pip you can path to your environment and type Scripts\python -m pip install <package> (noting that I have had trouble using Scripts\pip install <package> directly before; but given that the former has always worked, I haven't bothered to figure out why). Similarly, you can use the virtualenv python interpreter on the command line simply by typing Scripts\python.
You DON'T want to change your environmental settings to point to your virtualenv .exe because things can get pretty messed up that way. It also negates the point of keeping your python environments isolated.
As an aside - usually people interact with a virtualenv by "activating" it. This is optional and just puts everything relative to the Scripts folder (so you don't have to keep typing Scripts\ in front). The other benefit is that you can start pathing around to other directories and the command line will remember (while it is activated) that you want to use those particular versions of pip and python. If you're using the command line you can activate with Scripts\activate. If you're using PowerShell you'll need to use Scripts\activate.ps1. | 1 | 1 | 0 | I think I may have screwed myself.
I had pip working in my venv in PyCharm fine
but whenever I try to accsses pip from the powershell or cmd line, it doesn't recognize the command. I double checked the path variables and everything, and now further discouraged as the GUI platform I was working with wont open in the venv.
What are my options here? I need to get pip working in the powershell, it says it's there when I upgrade it, but says its missing when I try to use it, which is unbelievably frustrating. tried also uninstalling pip from the venv but that didn't help anything either. Any help is greatly appreciated.

Ordered by increasing insanity:
Some systems provide virtual files which contain various timers. You can get a sub-second resolution at least on a Linux system by reading a counter from that kind of file before and after execution. Not sure about others.
Can you reuse existing imports? If the file already contains any of threading, multiprocessing, signal, you can construct a timer out of them.
If you have some kind of scheduler running on your system (like cron) you can inject a job into it (by creating a file), which will print out timestamps every time it's run.
You can follow a log file on a busy system and assume the last message was close to the time you read it.
Depending on what accuracy you want, you could measure the amount of time each python bytecode operation takes, then write an interpreter for the code available via function.__code__.co_code. While you run the code, you can sum up all the expected execution times. This is the only pure-python solution which doesn't require a specific OS / environment.

The most useful thing I found is:
https://docs.anaconda.com/anaconda/user-guide/tasks/tensorflow/
which explains in very few steps how to install tf or tf-gpu in its own environment.
Then my problem was that the jupyter notebook is in its own base environment, not in the tf-gpu environment. How to work with that from a jupyter notebook based on the base environment?
The solution comes from the very helpful answer from Nihal Sangeeth to this question
https://stackoverflow.com/questions/53004311/how-to-add-conda-environment-to-jupyter-lab
conda activate tf-gpu
(tf-gpu)$ conda install ipykernel
(tf-gpu)$ ipython kernel install --user --name=<any_name_you_like_for_kernel>
(tf-gpu)$ conda deactivate
Close and reopen your jupyter notebook.
Then in your jupyter notebook you will find the option, under "kernel" of "change kernel". Change kernel to your newly created kernel and you will be able to import tensorflow as tf and go on from there.

Sure, they can download your script and run it themselves if they have a compatible version of Python installed, but you won't be able to run it from the browser (that would be a severe security problem!)
Your options are either to write it in JS, or create an API on your server, or find and use an existing API. | 1 | 0 | 0 | So, my project does a lot of mathematics for the user. It lets them enter equations and then solves them with some fairly complicated items like eigenvalues. I do some of this is javascript, but I have also written a python script utilizing numpy. I would like the user to be able to have the option of having the script on their local machine and then solving the mathematics there instead of on my server.
So, the user would enter an equation and hit enter. The javascript would then call a python script running on the users local machine. The equation is solved there with my code and the result is returned to the web page.
I thought that this would be possible with CGI, but I cannot seem to find clear documentation on how this would be accomplished. Is there a better way?
I do not want to run third party software and I do not want to run the python code in the browser.

At the core of all of them is to build heuristics and statistical models that can identify non-human-like behavior. Things such as:
Total number of requests from a certain IP per specific time frame, for example, anything more than 50 requests per second, or 500 per minute, or 5000 per day may seem suspicious or even malicious. Counting number of requests per IP per unit of time is a very common, and arguably effective, technique.
Regularity of incoming requests rate, for example, a sustained flow of 10 requests per second may seem like a robot programmed to make a request, wait a little, make the next request, and so on.
HTTP Headers. Browsers send predictable User-Agent headers with each request that helps the server identify their vendor, version, and other information. In combination with other headers, a server might be able to figure out that requests are coming from an unknown or otherwise exploitative source.
A stateful combination of authentication tokens, cookies, encryption keys, and other ephemeral pieces of information that require subsequent requests to be formed and submitted in a special manner. For example, the server may send down a certain key (via cookies, headers, in the response body, etc) and expect that your browser include or otherwise use that key for the subsequent request it makes to the server. If too many requests fail to satisfy that condition, it's a telltale sign they might be coming from a bot.
Mouse and keyboard tracking techniques: if the server knows that a certain API can only be called when the user clicks a certain button, they can write front-end code to ensure that the proper mouse-activity is detected (i.e. the user did actually click on the button) before the API request is made.
And many many more techniques. Imagine you are the person trying to detect and block bot activity. What approaches would you take to ensure that requests are coming from human users? How would you define human behavior as opposed to bot behavior, and what metrics can you use to discern the two?
There's a question of practicality as well: some approaches are more costly and difficult to implement. Then the question will be: to what extent (how reliably) would you need to detect and block bot activity? Are you combatting bots trying to hack into user accounts? Or do you simply need to prevent them (perhaps in a best-effort manner) from scraping some data from otherwise publicly visible web pages? What would you do in case of false-negative and false-positive detections? These questions inform the complexity and ingenuity of the approach you might take to identify and block bot activity. | 1 | 2 | 0 | I am learning python and i am currently scraping reddit.
