Hello, I found in the generation of hdf5 file steps in the input part of the video, the programme in the run to this step when "cnmfe_model.fit(images)" will produce "Singular matrix" If the downsampling time factor, downsampling spatial factor and background spatial downsampling factor, tsub, ssub, ssub_B, are changed to 2, then this error will not occur, but this will lose some data, so I am looking for help to find a way to not generate this error without changing these three parameters. Thank you very much!
Currently using the latest version of caiman.

Hello,
Is this happening with your data, or the sample data? Which notebook or code?
