Combining conda environment.yml with pip requirements.txt
提问by bastelflp
I work with conda environments and need some pip packages as well, e.g. pre-compiled wheels from ~gohlke.
我使用 conda 环境并且还需要一些 pip 包，例如来自~gohlke 的预编译轮子。
At the moment I have two files: environment.ymlfor conda with:
目前我有两个文件：environment.yml对于 conda 与：
# run: conda env create --file environment.yml
name: test-env
dependencies:
- python>=3.5
- anaconda
and requirements.txtfor pip which can be used after activating above conda environment:
和requirements.txt用于PIP可以上述环境康达激活后使用：
# run: pip install -i requirements.txt

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)?
是否有可能将它们组合在一个文件中（对于 conda）？

Pip dependencies can be included in the environment.ymlfile like this (docs):
Pip 依赖项可以environment.yml像这样 ( docs)包含在文件中：
# 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 .whlfiles in the same directory (see Dengar's answer) as well as with common pip packages.
它也适用.whl于同一目录中的文件（参见Dengar 的回答）以及常见的 pip 包。

Just want to add that adding a wheel in the directory also works. I was getting this error when using the entire URL:
只想补充一点，在目录中添加一个轮子也可以。使用整个 URL 时出现此错误：
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.
最终下载了轮子并将其保存到与 yml 文件相同的目录中。
name: test-env
dependencies:
- python>=3.5
- anaconda
- pip
- pip:
- opencv_python-3.1.0-cp35-none-win_amd64.whl

One can also use the requirements.txtdirectly in the YAML. For example,
也可以requirements.txt直接在 YAML 中使用。例如，
name: test-env
dependencies:
- python>=3.5
- anaconda
- pip
- pip:
- -r file:requirements.txt
Basically, any option you can run with pip installyou can run in a YAML. See the Advanced Pip Examplefor a showcase of other capabilities.
基本上，您可以使用的任何选项都可以pip install在 YAML 中运行。有关其他功能的展示，请参阅高级 Pip 示例。
