一种有线requirements.txt格式

Question

我从 github 存储库下载了一个 requriments.txt 文件，但我发现它与 requirments.txt 文件的正常格式略有不同。

1. 你能告诉我作者是如何生成这种requirments.txt的吗？ 通过哪些工具？
2. 我们如何使用这种 reuqirments.txt 格式来构建 python 环境？ 我已经在 Windows 平台上尝试了“conda install --file requirements.txt”或“pip install -r requirements.txt”，它们无法解决。

Answer 1

这看起来像一个 conda environment.yml文件。 它可以用来创建一个 conda 环境，就像这样

conda env create --file requirements.txt
