An error occurred when running mu.pp.neighbors()

Describe the bug An error occurred when running mu.pp.neighbors()

To Reproduce import anndata as ad import muon as mu

rna = ad.read_h5ad('SNARE_mousebrain_RNA.h5ad') atac = ad.read_h5ad('1SNARE_mousebrain_ATAC.h5ad') mdata = mu.MuData({"rna": rna, "atac": atac}) mu.pp.intersect_obs(mdata) mdata.shape mu.pp.neighbors(mdata, n_neighbors=20)

however, I get the following error message: Traceback (most recent call last): File "D:\PYTHON\lib\code.py", line 90, in runcode exec(code, self.locals) File "", line 1, in File "D:\PYCHARM\TREASMO\XUNI\lib\site-packages\muon_core\preproc.py", line 623, in neighbors mdata.obsp[conns_key] = connectivities File "D:\PYCHARM\TREASMO\XUNI\lib\site-packages\anndata_core\aligned_mapping.py", line 181, in setitem value = self._validate_value(value, key) File "D:\PYCHARM\TREASMO\XUNI\lib\site-packages\anndata_core\alig File "D:\PYTHON\lib\functools.py", line 875, in wrapper return dispatch(args[0].class)(*args, **kw) File "D:\PYCHARM\TREASMO\XUNI\lib\site-packages\anndata\utils.py", line 69, in dim_len return x.shape[axis] AttributeError: 'tuple' object has no attribute 'shape'

Expected behaviour can you tell me how can i solve it? Thank you!!!

System

• Windows11
• Python3.8
• anndata 0.9.2 muon 0.1.6
