ModuleNotFoundError: No module named '[x]'] #123

Open ikb42 opened 8 months ago

ikb42 commented 8 months ago

When the server has recently started and the Node app has recently started (specifically AWS Elastic Beanstalk new instance deployed)

When I call pd = await python('pandas'); I get an error like this: ModuleNotFoundError: No module named 'pandas'] This is despite there definitely being such a module, I am using the env variable PYTHON_BIN to set the path /usr/bin/python3.9

After some time, if I call this again it works. So I have setup a recursive function that on app start, calls await python over and over again (with a pause) until it succeeds, it seems to take about 5 mins to work. After that all works well.

Can you provide the stack trace for the error?
