Dependency in requirements.txt cannot be found on pypi

[XiangdongHe]

Thanks for your great work.

When using pip to install dependencies, I found that many packages cannot be found.
For example, we cannot find angles==1.9.13 on Pypi, but we can find versions 1.0, 1.1, and 2.0 of angles.

This situation exists for many packages in the requirements.txt file. What is the problem with this?
