My code works fine. It runs no issue when I run it through PyCharm (Python interpreter). I tried creating an executable of the program using a batch file. I have successfully created many executables using batch files, this is the first program not to work and the first program to use pandas.

Reproducing code example:

Batch file:
C:\Python38\Scripts\pyinstaller.exe ^
--hidden-import numpy ^
--hidden-import pandas ^
--hidden-import pandastable ^
--onefile ^
--distpath C:\Python38\Programs ^
--specpath C:\Python38\Programs\specs ^
--workpath C:\Python38\Programs\build ^
H:\Python#####\Update.py

Traceback (most recent call last):
  File "\\W16-CE-DC2\Users$\#####\Python\#####\Update.py", line 3, in <module>
    import pandas
  File "c:\python38\lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 621, in exec_module

ImportError: Unable to import required dependencies:
numpy:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
  1. Check that you expected to use Python3.8 from "C:\Python38\Programs\Update.exe",
     and that you have no directories in your PATH or PYTHONPATH that can
     interfere with the Python and numpy version "1.18.1" you're trying to use.
  2. If (1) looks fine, you can open a new issue at
     https://github.com/numpy/numpy/issues.  Please include details on:
     - how you installed Python
     - how you installed numpy
     - your operating system
     - whether or not you have multiple versions of Python installed
     - if you built from source, your compiler versions and ideally a build log

- If you're working with a numpy git repository, try `git clean -xdf`
  (removes all files not under version control) and rebuild numpy.

Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.

Original error was: DLL load failed while importing _multiarray_umath: The specified module could not be found.

### Numpy/Python version information:

Can you see if other issues mentioniong PyInstaller, such as #15299 help you? There was an issue with python 3.8 there, there are also some issues around PyInstaller picking up all the modules it needs to include correctly, due to its mechanism to do so being a brittle for NumPy.

I solved the issue. I had to downgrade to Python 3.7.6, re-download pyinstaller, and download all the modules again. Then the executable worked.
I wonder if there are still some bugs with Python 3.8

Thanks for the followup, closing, it seems like it is identical to gh-15229 anyway then.
