Hey @yxu148, thanks for reporting. I think this error is fixed in our latest version (5.3.2).
Since it's still not available in Anaconda, you need to create a new environment with conda-forge packages. For that, please close Spyder, open the Anaconda Prompt and run the following commands there:
conda create -n spyder-cf -c conda-forge spyder py-opencv
conda activate spyder-cf
spyder
Let us know if that solves the problem for you.
