IndexError: arrays used as indices must be of integer (or boolean) type

[Wangyananblink]

I am sorry to disturb you. I utilized the scaden to simulate a new h5ad file from the count.txt and the celltype.txt. But when I run the scaden process, I met "IndexError: arrays used as indices must be of integer (or boolean) type". When I utilize the h5ad generated by scanpy, the same question will appear. Could you give me any advice? Thank you in advance!
Here are related information.

Hi I'm having the same issue. I'm wondering if you have figured out how to solve it? Thanks !!

I encountered the same error and managed to solve it. In my case, this error did not stem from the h5ad file generated by 'scaden simulate,' but rather from the prediction data having an incorrect format, which led to the error report 'INFO Found 0 common genes. functions.py:88.' It seems the input prediction data (a gene * sample matrix table) should be written with '\t' as the separator and without quotation marks. I resolved this error by preparing my prediction data in R using the following code: 'write.table(prediction_data, path, sep = "\t", quote = FALSE)'. Hope it will be helpful.
