Hello,
I am trying to run mnnpy.mnn_correct on 2 anndata objects. The code works until the last step of packing AnnData and I get the error: AttributeError: Can only use .str accessor with string values!
Here is the output from the function:
Performing cosine normalization...
Starting MNN correct iteration. Reference batch: 0
Step 1 of 1: processing batch 1
Looking for MNNs...
Computing correction vectors...
Adjusting variance...
Applying correction...
MNN correction complete. Gathering output...
Packing AnnData object...

Has anyone encountered this and if so, does anyone know how I can fix this? The datatypes of the obs and vars in the individual anndata objects are strings, so do not know what this is referring to
