Ubuntu – Connecting Alpaca to Python in AWS

I am creating a program to simulate stock trading with an Alpaca paper trade account but I’m not able to get my program to work with Alpaca.

I have installed the module the documentation says to install using pip3 install alpaca_py it says it is successful, but then when I try to import it and use my API keys it gives an error that the module is not found.

Here is the code I’m trying to use (only with my actual keys):

import alpaca_py as tradeapi

# Set your Alpaca API key and secret
api_key= "api_key_here"
api_secret = "api_secret_here"

# Set the base URL for paper trading
base_url = "https://paper-api.alpaca.markets"

# Create an Alpaca API connection
api = tradeapi.REST(api_key, api_secret, base_url=base_url, api_version='v2')

This is the error I’m getting:

Traceback (most recent call last):
  File "/home/ubuntu/environment/final_play.py", line 2, in <module>
    import alpaca_py as tradeapi
ModuleNotFoundError: No module named 'alpaca_py'

I found a couple other articles about this, but they both mentioned it being an issue with a file sharing the name of the module. I do not have a file named alpaca.py, just final_play.py

pip install alpaca-py doesn’t work to install. the output when I use this is below:

ubuntu:~/environment $ pip install alpaca-py

    After further research, it seems the module alpaca-py isn't functional. I was able to install alpaca_trade_api using pip3 install alpaca_trade_api and the following code to get the connection I needed.

    import alpaca_trade_api as tradeapi

# Set your Alpaca API key and secret
api_key= "#api-key-here#"
api_secret = "#secret-key-here#"

# Set the base URL for paper trading
base_url = "https://paper-api.alpaca.markets"

# Create an Alpaca API connection
api = tradeapi.REST(api_key, api_secret, base_url=base_url, api_version='v2')

    The alpaca-py module is functional. In the code you provided, it isn’t being called in the proper manner.

    After it is installed with pip3 install alpaca-py, the name of the module is just ‘alpaca’.

    When called in the proper manner, you can access the trade api like so:

    from alpaca.trading.client import TradingClient

trading_api = TradingClient(
    api_key='<KEY_ID>',
    secret_key='<SECRET_KEY>',
    paper=True
)

    Documentation Link: https://alpaca.markets/sdks/python/trading.html

    I would recommend using the alpaca-py module since it is the new Python SDK that Alpaca has created.
