Error in `mode.preprocess` step

[BioinfoTongLI]

Hello there!

I have an issue running the preprocess step in the tutorial and the error log is:

### pct_filter: percent of spots filtered out

### default: filter 10% spots out

pct_filter=0.1

model.preprocess(pct_filter)

---------------------------------------------------------------------------

    160 

IndexError: only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or boolean arrays are valid indices

Is it because no nculei were detected here?
If so, is there any possibility to send DAPI label image instead of the raw?

Thanks for your help!

Best,
