ERROR: Directory is not installable. Neither 'setup.py' nor 'pyproject.toml'

Question

I've got the following error:

ERROR: Directory is not installable. Neither 'setup.py' nor 'pyproject.toml'

Background is that I'm following a guide online to expose an ML model via API Gateway on AWS that can be found here: Hosting your ML model on AWS Lambdas + API Gateway

I'm trying to pull some python packages into a local folder using the following command:

pip install -r requirements.txt --no-deps --target python/lib/python3.6/site-packages/

I have also tried this:

pip install -r requirements.txt --no-deps -t python/lib/python3.6/site-packages/

and all I get is the above error. Google is pretty bare when it comes to help with this issue, any ideas?

thanks,

Answer 1

Please try this:

   ADD requirements.txt ./
   pip install -r requirements.txt --no-deps -t python/lib/python3.6/site-packages/

syntax: ADD source destination

'ADD requirements.txt ./' adds requirements.txt (assumed to be at the cwd) to the docker image's './' folder.

Thus creating a layer from which the daemon has the context to the location of requirements.txt in the docker image.
