Add collect PyTables library to PyInstaller SPEC File

I am using PyInstaller to build an executable of a python script containing PyTables. Since I've updated to the newest version, building the executable fails. The error reads:

Error: RuntimeError: Blosc2 library not found. I looked for "libblosc2.dll, C:\Users\USER\AppData\Local\Temp_MEI10642\tables\libblosc2.dll, None"

According to this post, adding tables binary is now needed: https://github.com/pyinstaller/pyinstaller/issues/7408

I have a SPEC-File and dont know how to add the missing library. I've tried the following:

So I am trying to add

Case 1:

binaries=[('C:\\Python39\\bin\\libblosc2.dll', 'BINARY')]

Error:

RuntimeError: Blosc2 library not found. I looked for "libblosc2.dll, C:\Users\USER\AppData\Local\Temp\_MEI10642\tables\libblosc2.dll, None"

Case 2:

binaries=[('C:\\Python39\\bin\\libblosc2.dll', '.')]

The loader hangs in a loop and not starting the executable.

So, how do I add the "Just add --collect-binaries=tables to your pyinstaller command" properly to my SPEC-File?

Thanks!

I also have the same problem. --collect-binaries=tables only works for command line. To resolve this issue, you can add the following to your app.spec file:

from PyInstaller.utils.hooks import collect_dynamic_libs

binaries = []
binaries += collect_dynamic_libs('tables')

a = Analysis(
    ...
    binaries=binaries,
    ...
)

If you encountered loader stuck in loop after successfully building the app, you can see the following issue Loader stuck in loop with PyTables
