This is useful because (1) plugins use OpenAPI endpoints under the hood, (2) wrapping them in an NLAChain allows the router agent to call it more easily.The novel idea introduced in this notebook is the idea of using retrieval to select not the tools explicitly, but the set of OpenAPI specs to use. We can then generate tools from those OpenAPI specs. The use case for this is when trying to get agents to use plugins. It may be more efficient to choose plugins first, then the endpoints, rather than the endpoints directly. This is because the plugins may contain more useful information for selection.Set up environment​Do necessary imports, etc.from langchain.agents import ( Tool, AgentExecutor, LLMSingleActionAgent, AgentOutputParser,)from langchain.prompts import StringPromptTemplatefrom langchain import OpenAI, SerpAPIWrapper, LLMChainfrom

This notebook was originally published at filipmichalsky/SalesGPT by @FilipMichalsky.SalesGPT is context-aware, which means it can understand what section of a sales conversation it is in and act accordingly.As such, this agent can have a natural sales conversation with a prospect and behaves based on the conversation stage. Hence, this notebook demonstrates how we can use AI to automate sales development representatives activites, such as outbound sales calls. Additionally, the AI Sales agent has access to tools, which allow it to interact with other systems.Here, we show how the AI Sales Agent can use a Product Knowledge Base to speak about a particular's company offerings,

However, their success heavily relies on human input to guide the conversation, which can be challenging and time-consuming. This paper explores the potential of building scalable techniques to facilitate autonomous cooperation among communicative agents and provide insight into their "cognitive" processes. To address the challenges of achieving autonomous cooperation, we propose a novel communicative agent framework named role-playing. Our approach involves using inception prompting to guide chat agents toward task completion while maintaining consistency with human intentions. We showcase how role-playing can be used to generate conversational data for studying the behaviors and capabilities of chat agents, providing a valuable resource for investigating conversational language models. Our contributions include introducing a novel communicative agent framework, offering a scalable approach for studying the cooperative behaviors and capabilities of multi-agent systems, and open-sourcing our library to support research on communicative agents and beyond.The original implementation: https://github.com/lightaime/camelProject website: https://www.camel-ai.org/Arxiv paper:

We need to pass the period for the short-term moving average and the period for the long-term moving average as arguments to this function. We can use the following code to calculate the short-term and long-term moving averages: ``` short_ma = ta.SMA(df['close'], timeperiod=short_period) long_ma = ta.SMA(df['close'], timeperiod=long_period) ``` This will calculate the short-term and long-term moving averages for the stock data and store them in the `short_ma` and `long_ma` variables, respectively. Next request. AI User (Stock Trader): Instruction: Create a new DataFrame that combines the historical stock data with the short-term and long-term moving averages. Input: None. AI Assistant (Python Programmer): Solution: We can create a new DataFrame that combines the historical stock data with the short-term and long-term moving averages using the `concat()` function from pandas. We need to pass the historical stock data, the short-term moving average, and the long-term moving average as arguments to this function. We can use the following code to create
https://python.langchain.com/docs/use_cases/agents/camel_role_playing
d247d4d249a8-10
and the long-term moving average as arguments to this function. We can use the following code to create the new DataFrame: ``` new_df = pd.concat([df, short_ma, long_ma], axis=1) new_df.columns = ['open', 'high', 'low', 'close', 'volume', 'short_ma', 'long_ma'] ``` This will create a new DataFrame called `new_df` that combines the historical stock data with the short-term and long-term moving averages. The columns of the new DataFrame are named 'open', 'high', 'low', 'close', 'volume', 'short_ma', and 'long_ma'. Next request. AI User (Stock Trader): Instruction: Create a new column in the DataFrame that indicates when to buy or sell the stock based on the crossover of the short-term and long-term moving averages.

We can use the following code to create the new column: ``` new_df['signal'] = np.where(new_df['short_ma'] > new_df['long_ma'], 1, -1) ``` This will create a new column called 'signal' in the DataFrame that indicates when to buy or sell the stock based on the crossover of the short-term and long-term moving averages. If the short-term moving average is greater than the long-term moving average, the signal is 1 (buy), otherwise the signal
https://python.langchain.com/docs/use_cases/agents/camel_role_playing
d247d4d249a8-11
is greater than the long-term moving average, the signal is 1 (buy), otherwise the signal is -1 (sell). Next request. AI User (Stock Trader): Instruction: Create a new column in the DataFrame that indicates the profit or loss for each trade based on the buy and sell signals and the defined stop loss and profit target. Input: The stop loss and profit target as percentages. AI Assistant (Python Programmer): Solution: We can create a new column in the DataFrame that indicates the profit or loss for each trade based on the buy and sell signals and the defined stop loss and profit target. We need to pass the stop loss and profit target as percentages as arguments to this function. We can use the following code to create the new column: ``` stop_loss = stop_loss_percent / 100 profit_target = profit_target_percent / 100 new_df['pnl'] = 0.0 buy_price = 0.0 for i in range(1, len(new_df)): if new_df['signal'][i] == 1 and new_df['signal'][i-1] == -1: buy_price = new_df['close'][i] elif new_df['signal'][i] == -1 and new_df['signal'][i-1] == 1: sell_price = new_df['close'][i] if sell_price <= buy_price * (1 - stop_loss):
https://python.langchain.com/docs/use_cases/agents/camel_role_playing
d247d4d249a8-12
if sell_price <= buy_price * (1 - stop_loss): new_df['pnl'][i] = -stop_loss elif sell_price >= buy_price * (1 + profit_target): new_df['pnl'][i] = profit_target else: new_df['pnl'][i] = (sell_price - buy_price) / buy_price ``` This will create a new column called 'pnl' in the DataFrame that indicates the profit or loss for each trade based on the buy and sell signals and the defined stop loss and profit target. The stop loss and profit target are calculated based on the stop_loss_percent and profit_target_percent variables, respectively. The buy and sell prices are stored in the buy_price and sell_price variables, respectively. If the sell price is less than or equal to the stop loss, the profit or loss is set to -stop_loss. If the sell price is greater than or equal to the profit target, the profit or loss is set to profit_target. Otherwise, the profit or loss is calculated as (sell_price - buy_price) / buy_price. Next request. AI User (Stock Trader): Instruction: Calculate the total profit or loss for all trades. Input: None. AI Assistant (Python Programmer): Solution: We can calculate the total profit or loss for all trades by summing the values in the 'pnl' column of the DataFrame. We can use
https://python.langchain.com/docs/use_cases/agents/camel_role_playing
d247d4d249a8-13
trades by summing the values in the 'pnl' column of the DataFrame.
