I can not load the Kilosort2 output into the GUI. I pasted the error below. Should I try to run Kilosort with a different configuration so the output is somehow smaller? I have not had this problem before, using the same type of recordings, and similar data sizes.
Best

Can you double check that you have a 64-bit installation of Python? You can also do
python -c 'import sys;print("%x" % sys.maxsize, sys.maxsize > 2**32)'
Great! You were right.
It was different computer with a 32-bit version of python.
thank you very much!
