Why Do I get an ImportError when building a .exe with pyinstaller?

Question

I just created a small GUI program that compiles and works fine in IPython, but when I try to export it to a .exe using pyinstaller it gives me an import error.

Answer 1

Find this dir "E:\Anaconda3\Lib\site-packages\PyInstaller\hooks". Add a file "hook-pandas.py",wrie this content to this file:

"""
Hook for pandas. 
Suport for pyinstaller error : No module named ‘pandas._libs.tslibs.timedeltas
"""
hiddenimports=[
    #all your previous hidden imports
    'pandas', 'pandas._libs.tslibs.timedeltas',
    'sklearn.neighbors.typedefs'
]

Then use this command:

pyinstaller -F myfile.py --hidden-import sklearn.neighbors.typedefs

Then it will be OK!
