type error line 499 when running in jupyter notebook

Got this error when running your code ... not sure how to fix it.
Also, received another error related to np.float which is deprecated and can be changed to np.float64 which seemed to work.

Hi @rwnull ,
I have met the same error with @PMaye. Do you have any solutions?
Hope to your reply. Many thanks to this helpful tool.

Good day,

I am also getting that same error. I have noticed that its appearance seems to depend on the max number of probes I set when running blast vs. transcriptome. Any ideas?

Cheers,
J.
