结合conda环境。Yml和PIP requirements.txt

小开

最佳答案

Pip依赖关系可以像这样包含在environment.yml文件中(文档):

# run: conda env create --file environment.yml
name: test-env
dependencies:
- python>=3.5
- anaconda
- pip
- numpy=1.13.3  # pin version for conda
- pip:
# works for regular pip packages
- docx
- gooey
- matplotlib==2.0.0  # pin version for pip
# 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下的.whl文件(参见波巴的回答)以及普通pip包。

只是想添加，在目录中添加一个轮子也可以工作。我得到这个错误时，使用整个URL:

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

最后下载了轮子，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

小开

也可以在YAML中直接使用requirements.txt。例如,

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

基本上，可以使用pip install运行的任何选项可以在YAML中运行。参见高级Pip示例展示其他功能。

重要提示

这个答案的前一个版本(以及Conda的高级Pip示例)使用了不符合标准的file URI语法:

    - -r file:requirements.txt

Pip v21.2.1为URI解析引入了更严格的行为，并且不再支持它。看到这是详细的答案。

小开

如果你想自动完成它，似乎如果你这样做:

conda env export > environment.yml`

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

  - pip:
- -r file:requirements.txt

正如另一个回答提到的。
