adding the langchain folder in the spec file using the line below works: a.datas += Tree('path/to/folder', prefix='langchain')

I think changing to `datas += collect_data_files('langchain')` to `datas += Tree('path/to/folder', prefix='langchain')` should work

to run `PyInstaller` with the `spec-file` use `py -m PyInstaller name_of_spec-file`. Use the path to the actual folder, so `G:\DEV\.venv\langchain\Lib\site-packages\langchain`

the line `a.datas += Tree('path//to//langchain', prefix='langchain')` is missing in your spec file

when you run the exe-file, there should be a temporary folder in AppData/local (I think), where all the data from the program is stored. If the package `sentence-transformers` is not...
