Question

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。

目前我有两个文件：environment.yml for conda with：

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

和requirements.txt可以在激活上述conda环境后使用pip：

# 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

是否有可能将它们合并到一个文件中（对于conda）？

Answer 1

Pip依赖项可以包含在environment.yml文件中，如下所示（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

它也适用于同一目录中的.whl个文件（请参阅Dengar's answer）以及常见的pip包。

Answer 2

只想添加在目录中添加一个轮子也可以。使用整个网址时出现此错误：

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

结束下载轮并将其保存到与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

Answer 3

一个人也可以直接在YAML中使用requirements.txt。例如，

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

基本上，您可以使用pip运行的任何命令都可以在YAML中运行。有关其他功能的展示，请参见the Advanced Pip Example。

Answer 4

如果你想自动执行它似乎如果你这样做：

conda env export > environment.yml`

已经有了你需要的 pip 东西。无需为我单独运行 pip freeze > requirements4pip.txt 或将其作为

  - pip:
    - -r file:requirements.txt

正如提到的另一个答案。

请注意，在撰写本文时，执行 conda env create --file environment.yml 来创建 yml env 会导致错误：

$ conda env create --file environment.yml

CondaValueError: prefix already exists: /home/miranda9/miniconda3/envs/myenv

将conda environment.yml与pip requirements.txt结合使用
