This is a bug in cx_Freeze – it doesn’t automatically detect that it should copy the module numpy.lib.format
. It’s already fixed in the development version, so if you’re in a position to try that, it should work.
Otherwise, you’ll need to specify that numpy.lib.format
needs to be included in your setup.py
. The line will look something like this:
options = {"build_exe": {"packages": ["numpy.lib.format"]}},
