------------------------------------------------------------------
I believe that I identified how to fix this issue.
To install {{Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017
and 2019.}} from
[https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads]
avoids this error.
I think that this problem does not occur with conda. This problem occurs with
only pip.
The following is my validation step. If someone double-checks it, we would
appreciate it.
