An error when running bbknn$bbknn(adata,batch_key=0)

Hi @Teichlab,

I want to use bbknn in R. But an error come out as follow:
`

bbknn = import(module = 'bbknn')
sc = import("scanpy",convert=FALSE)
np = import("numpy")
scipy = import("scipy")
b <- brca[[1]]
pca.input <- b@reductions$pca@cell.embeddings
batches <- b@meta.data$sample
adata <- anndata$AnnData(X = pca.input, obs = batches)
sc$tl$pca(adata)
None
adata$obsm$X_pca <- r_to_py(pca.input)
bbknn$bbknn(adata, batch_key = 0)

*** caught illegal operation ***
address 0x2b6db2dc781d, cause 'illegal operand'

Traceback:
1: py_call_impl(callable, dots$args, dots$keywords)
2: bbknn$bbknn(adata, batch_key = 0)

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace

Could you please help me figure out this problem?

Thanks a lot

Best
