Cannot open flika on macOS Catalina

[csamuel11]

I am using a mac with macOS Catalina. I am using anaconda to access python. In the terminal, I typed "pip install flika" as directed. Then, I typed "ipython". Finally, I typed "from flika import *", then "start_flika()". Up to this point everything is okay. However, after clicking return, I get a long string a text that ends with the following: KeyError: 'Unknown configuration option "useWeave"'. Could you please help? I attached the code in a Word document. error.docx

Hi there, I'm encountering a similar problem as csamuel11: when I launch flika from a notebook I get the error posted below which ends with: KeyError: 'Unknown configuration option "useWeave"'

~/anaconda3/lib/python3.9/site-packages/flika/window.py in <module>
     11 from .utils.BaseProcess import WindowSelector, SliderLabel
     12 
---> 13 pg.setConfigOptions(useWeave=False)

Could this be because of version incompatibilities?

I have the following versions installed:

flika 0.2.30 pyqt 5.9.2 py37h05f1152_2
pyqt5 5.15.4 pypi_0 pypi pyqt5-qt5 5.15.2 pypi_0 pypi pyqt5-sip 12.8.1 pypi_0 pypi pyqtgraph 0.12.1 pypi_0 pypi

Really appreciate any support on this (this package is really helpful for my work).

Thanks,

Weiyu

Thanks for the descriptions. I was able to recreate this error on a fresh install, and have fixed it in version 0.2.33. The cause was pg.setConfigOptions(useWeave=False) passed a configuration option that no longer works in the newer version of pyqtgraph. I'll close this issue now, but feel free to open if it you run into more issues.
