can't import pyqtgraph

[Raziel Itzhak]

I have Python 3.9.12 and I  just installed pyqtgraph but I can't start to work with it.

I get the following error:

ValueError: PyCapsule_GetPointer called with incorrect name

How can I fix this error so I could start to work whit pyqtgraph?

Hey,

I couldn't reproduce your issue, but a cursory web search suggests you should downgrade your version of pyqt. Do you have any more details to help us? What kind of python environment are you using?

Good luck!

Thanks for your comment.

I have spyder version 5.1.5, Python  3.9.12, PyQt5, and windows 10 64-bit.

 I downrange to  - pip install pyqtgraph==0.11.0 and now it is working.

I have no idea why the last version didn't work;/

Thank you!

What version of PyQt5 do you have?  If you have a conda environment, can you show us the output of conda list?  Otherwise show us pip list?

Hi,

here is the outcome of pip list:

PyQt5-Qt5                          5.15.2
PyQt5-sip                          12.11.0
pyqtgraph                          0.12.4

when I import pyqtgraph I get the following:

import pyqtgraph
Traceback (most recent call last):

  File "C:\Users\iraziel\AppData\Local\Temp/ipykernel_15584/2157412210.py", line 1, in <module>

    from .Qt import QtGui, mkQApp

    from PyQt5 import QtTest

Can you provide the entire output of your pip/conda list?  There's something weird happening as I've never seen this before.
