FileNotFoundError: [Errno 2] No such file or directory: '<dir_path>/pattern/text/en/en-model.slp'

I have also tried with pip3 as well as python3 setup.py install. No luck on any of this.

The pattern library uses sys.path manipulations which sometimes don't work smoothly with PyInstaller (https://pyinstaller.readthedocs.io/en/stable/operating-mode.html)

I came up with a temporary fix which works for me smoothly. There might be a better way to solve it though:

1. Instead of importing "pattern.en", import "pattern.text.en" as this is actually how it appears
2. The executable was unable to find "en-model.slp" file. In the '<dir_path>/pattern/text/en/init.py', en-model.slp is defined as model = os.path.join(MODULE, "en-model.slp")
3. At the top of the init.py where MODULE variable is defined, I temporality changed variable to empty string so that the executable finds the .slp file in the current directory (like this, MODULE = "").
4. After the executable is created, I copied the "en-model.slp" file to the same dist directory where my executable is created. This way my executable started working.
5. Reverted back all the changes in init.py
