ModuleNotFoundError: No module named 'bleak'

[daxiong2009]

i was testing a simple program that connect and read a bluetooth device using bleak package. the program run normally with .py file but fail to run .exe as the bleak can not be imported. Later i added the multiprocessing part, but the issue is still there.

i think mine is the same as #8395, but could not fix the issue. Please help

If you want help then we need code (I can't run a screenshot) and an error message.

[daxiong2009]

sorry, here is the code:

if __name__ == '__main__':
    import multiprocessing
    multiprocessing.freeze_support()


import asyncio
import bleak


address = "04:EE:03:5A:52:1B"
uuid = "00002a58-0000-1000-8000-00805f9b34fb"
runtime = 10

async def main():
    async with bleak.BleakClient(address) as client:
            print(f"Connected to the device: {address}")
            task = asyncio.create_task(client.start_notify(uuid, emg_changed))
            print("Notifications started...")
            await task
            # following two lines of code can be replaced with block comment if want to run device forever
            await asyncio.sleep(runtime)
            await client.stop_notify(uuid)


def emg_changed(handle, data):
    data_convert = int.from_bytes(data, "little", signed=False)
    print(data_convert)


if __name__ == '__main__':
    asyncio.run(main())

If this is with onefile mode and if that screenshot contains all the code there is, then the issue might be that the main process is not waiting for the spawned child process to finish. So it exits right after spawning the child process, which triggers cleanup of the temporary directory by the onefile parent, and so the spawned child process might end up without files.

where to get full error message? sorry i am new to pyinstaller

You are saying that the bleak module cannot be imported (ModuleNotFoundError: No module named 'bleak') - where are you seeing this error?

Presumably when you run your program? In that case, you should get full traceback as well, either in console window (if your program is console-enabled and you run it in command prompt) or in unhandled exception error dialog (if you are using noconsole/windowed build).

[rokm]

Note that the warnings in warn-xx file are not necessarily issues (especially for conditional imports), and you can ignore them if the generated executable runs without errors.

this should be the full error message. i paste part of them here , i also attach the full log txt file down here

Any difference if you add --hiddenimport winrt.windows.foundation.collections to your PyInstaller command (or if you are building with .spec, if you add that module to hiddenimports list)?

[rokm]

If you subsequently get errors for other modules from winrt.windows.foundation, you can try using --collect-submodules winrt.windows.foundation instead. EDIT: nevermind, I see that it's the only submodule there.

that works! thanks a lot!
