I've been trying to create an exe file from my py files. There are multiple py files, however, 1 entry point file. My code takes input from html, csv, xml files and generate a word file as an output.
I'm using Python 3.9, tried using Pyinstaller 4.2, 5(dev). Both giving the same error. Conversion is successful if I try to convert a file without matplotlib in it. I've tried different versions of matplotlib also. Specifically, 4.3.1, 4.3.0rc1, 3.2.2. However, everytime I'm getting the same error.
assert mpl_data_dir, "Failed to determine matplotlib's data directory!"
AssertionError: Failed to determine matplotlib's data directory!
I've also tried to make changes to the hook files as well, according to similar problem faced by other people, however, still the same problem persists.

The most common reason a PyInstaller package fails is that PyInstaller failed to bundle a required file. Such missing files fall into a few categories: Hidden or missing imports: Sometimes PyInstaller can't detect the import of a package or library, typically because it is imported dynamically.
They do not need to have Python installed at all. The output of PyInstaller is specific to the active operating system and the active version of Python. This means that to prepare a distribution for: a different OS.
It's an error caused by the pyinstaller matplotlib hook, for some reason the exec_statement () function that is supposed to be getting the data path is not working. This is what worked for me: Go to the folder where pyinstaller is installed. Go to the hooks folder. Locate and open hook-matplotlib.py file.
Pyinstaller is a python module using which the python file (.py) can be converted to an executable file (.exe). Install the pyinstaller directly on the default environment using the below command.
I tried changing the hook-matplotlib.py file as others suggested, but it turns out the newest version of Pyinstaller already has these changes, so as long as your pyinstaller is updated, you should be fine in that aspect (check by running pip install pyinstaller --upgrade)
In this tutorial, we will talk about converting the python to exe file and then creating a setup that can be installed.

Thanks to wedesoft:
pip uninstall pathlib
did the job. I replaced pathlib code with os.path; everything works perfect.
NOTICE: Updating matplotlib or pyinstaller didn't help me. I'm sure it'll be fixed in the newer pyinstaller version. More about the same issue here:

If you followed correctly, your code should look like this:
import matplotlib
mpl_data_dir = matplotlib.get_data_path()
datas = [
(mpl_data_dir, "matplotlib/mpl-data"),
]
I don't understand why, but the issue was solved when we installed matplotlib==3.0.2 and pyinstaller==4.2
