使用 pip 从源代码安装和构建多个包

Question

I want to create a Python package. To make this work, the user needs to install multiple python packages. I also need the user to install a package that is currently only supported for installing straight from the source (ie pip install -e. ). How do I create my own source package, which depends on another source package in a clean way? In my opinion, it would be best if the user can just run python setup.py once; which installs my package and all the requirements in requirements.txt as well as the other package straight from the source.

I added a setup.py file with the following content:

setuptools.setup(
    dependency_links=["git+https://github.com/facebookresearch/pytorch-dp.git#egg=pytorch-dp"],
    packages=setuptools.find_packages(),
    python_requires=">=3.6",
)

When I run the setup file I get:

Moving pytorch_dp-0.1-py3.6.egg to /usr/local/lib/python3.6/dist-packages
Adding pytorch-dp 0.1 to easy-install.pth file

but then if I try to import the package torchdp :

import torchdp

I get the error: ModuleNotFoundError: No module named 'torchdp'

I'm using a Google Colab Notebook for GPU support.*

Turned out I had to restart google colab, and then it worked. Yikes.
