ImportError: DLL load failed with Windows wheel for 1.0.2 and 1.0.3
When trying to install `pandas 1.0.2` or newer versions on a docker, I run into the following import error:

```

```

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

```cmd
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
```
