ImportError: DLL load failed with Windows wheel for 1.0.2 and 1.0.3

See original GitHub issue

When trying to install pandas 1.0.2 or newer versions on a docker, I run into the following import error:

Traceback (most recent call last):

    import pandas._libs.window.aggregations as window_aggregations
ImportError: DLL load failed while importing aggregations: The specified module could not be found.

I’ve reproduced this error on a separate pc by running:

docker run -it python cmd.exe
pip install pandas
python
import pandas

This error only occurs when trying to import pandas from the docker. Python and pip versions:

python 3.8.2
pip 20.0.2

I just installed python3.8 on a completely fresh installation of Windows 10 1909 and ran into this issue. All I had to do was install the lastest x64 version of the visual c redistributable vc_redist from here and my import problem went away.

On a docker image with python 3.7.8 and Windows-10-10.0.17763-SP0, we can reproduce the DLL error with pandas==1.0.5, and in a fresh instance get no error with pandas==1.1.0.rc0 🥳
