Input X contains NaN. #678

Open christophechu opened 3 months ago

christophechu commented 3 months ago

dyn.tl.cell_velocities(adata, method='kmc', other_kernels_dict={'transform': 'sqrt'}) raise 'Input X contains NaN.'

Sichao25 commented 3 months ago

Hi, thanks for raising this issue. Basically, this error occurs when there are NaN values in your dataset (Could be either in expression or velocity matrix). Could you share additional details about your issue(e.g. the dataset you are working with, previous steps you've performed, relevant traceback ...)?

It should by definition not have any NA value. But I don't know why this problem has arisen.

adata_raw = adata.copy() preprocessor = dyn.pp.Preprocessor(cell_cycle_score_enable=True) preprocessor.config_monocle_recipe(adata_raw) preprocessor.filter_cells_by_outliers_kwargs["keep_filtered"] = False preprocessor.filter_genes_by_outliers_kwargs["inplace"]=True preprocessor.select_genes_kwargs["n_top_genes"]=3000 preprocessor.preprocess_adata_monocle(adata_raw) adata = adata_raw.copy() adata.raw = adata del adata_raw

Would you mind sharing the traceback information? This will help us better locate the error.
