ImportError: cannot import name 'QObject' from 'PyQt5.Qt

[ShahriyarB]

No matter which version of Python or IDA Pro I use I get this error when I launch IDA Pro with daila plugin Tested on IDA Pro 7.5, 7.7 and 9.0 Tested with Python 3.9, 3.10, 3.11 and 3.12

@ShahriyarB it looks like your IDA install may be corrupted in some way. To verify it is, try and go into the IDA terminal and write from PyQt5.Qt import QObject. This should never fail since QT5 is bundled with IDA.

First: Thanks for the plugin!

I have the error in 8.3 as well. Testing from PyQt5.Qt import QObject works OK AFAICS.

@BeErikk hmmm ok. Since this is twice now, and you are both on Windows, I'll investigate some. Considering the import works in the terminal, this must be some timing-based error of when we can load the UI.

[mahaloz]

59 fixed it on my machine. Updating to version 3.8.1 hopefully fixes it. Please reopen if it does not.

[BeErikk]

Thanks for your effort, but the error persist for me. I exchanged the plugin/daila_plugin.py with the latest version. Is there a good way to reinstall the plugin?

[mahaloz]

@BeErikk to update you need to do py -m pip install -U dailalib. The daila_plugin.py is just a stub for the Python backend.

[BeErikk]

Thanks (I know nothing about Python). There are still errors but with different messages. I think this error has been up before with a possible solution to upgrade Python. However, I don't think an upgrade will solve anything in my case:

python --version
Python 3.12.2

@BeErikk can you try these two possible things:

1. Switch python version, I have not tested on 3.12, and others have reported some crashing
2. pip install sip

[m-kozlowski]

There should be idapyswitch.exe bundled with IDA. Run it and select correct version of your python installation, it should replace .pyd files with correct ones.

[mahaloz]

Wow, it's unexpected that this is another idapyswitch problem. Ha.
