Python code runs tensorflow-gpu 2.5, but the executable only runs with CPU!!

[aziabari]

My python code runs on multiple GPUs and runs perfectly with tensorflow-gpu.

Then I tried to package it with pyinstaller, but I got tensorflow issues.
I added a tensorflow hook (as follows) and resolved the issue.

from PyInstaller.utils.hooks import collect_all

def hook(hook_api):
packages = [
'tensorflow']
for package in packages:
datas, binaries, hiddenimports = collect_all(package)
hook_api.add_datas(datas)
hook_api.add_binaries(binaries)
hook_api.add_imports(*hiddenimports)

However, after creating and running the executable, it only runs on CPU.

• OS: Ubuntu
• Python Version: python 3.8
• tensorflow-gpu: 2.5
• Version of PyInstaller 4.2
