pandas: Pandas 0.23.0 gives ImportError: DLL load failed

Installed pandas not able to import with:

ImportError: DLL load failed: The specified module could not be found.

As far as we know, this happens if you install with pip on Windows 32bit machines (if you have another case, please comment below with specifying your OS, Python version, how you installed pandas, …).

Workaround for now is to keep your version at pandas 0.22.0. (or to install using conda, or to install VS tools for C++, see https://github.com/pandas-dev/pandas/issues/21106#issuecomment-391459521)

We will fix this problem for 0.23.1.
