结合conda environment.yml和pip requirements.txt

I work with conda environments and need some pip packages as well, e.g. pre-compiled wheels from ~gohlke.

At the moment I have two files: environment.yml for conda with:

# run: conda env create --file environment.yml
name: test-env
dependencies:
- python>=3.5
- anaconda

and requirements.txt for pip which can be used after activating above conda environment:

# run: pip install -i requirements.txt
docx
gooey
http://www.lfd.uci.edu/~gohlke/pythonlibs/bofhrmxk/opencv_python-3.1.0-cp35-none-win_amd64.whl

Is there a possibility to combine them in one file (for conda)?

Pip dependencies can be included in the environment.yml file like this (docs):

# run: conda env create --file environment.yml
name: test-env
dependencies:
- python>=3.5
- anaconda
- pip
- pip:
  # works for regular pip packages
  - docx
  - gooey
  # and for wheels
  - http://www.lfd.uci.edu/~gohlke/pythonlibs/bofhrmxk/opencv_python-3.1.0-cp35-none-win_amd64.whl

It also works for .whl files in the same directory (see Dengar’s answer) as well as with common pip packages.

One can also use the requirements.txt directly in the YAML. For example,

name: test-env
dependencies:
  - python>=3.5
  - anaconda
  - pip
  - pip:
    - -r file:requirements.txt

Basically, any option you can run with pip install you can run in a YAML. See the Advanced Pip Example for a showcase of other capabilities.

Just want to add that adding a wheel in the directory also works. I was getting this error when using the entire URL:

HTTP error 404 while getting http://www.lfd.uci.edu/~gohlke/pythonlibs/f9r7rmd8/opencv_python-3.1.0-cp35-none-win_amd64.whl

Ended up downloading the wheel and saving it into the same directory as the yml file.

name: test-env
dependencies:
- python>=3.5
- anaconda
- pip
- pip:
  - opencv_python-3.1.0-cp35-none-win_amd64.whl
