Hi,
I 'm getting an error when I use the R integration part. The vesion is 1.5.7.
after I run transcript_py <- cc$get_transcriptomics() :

Error in py_call_impl(callable, call_args$unnamed, call_args$named) : TypeError: object of type 'generator' has no len() Run reticulate::py_last_error() for details.

Details goes as below:

── Python Exception Message ───────────────────────────────

Thanks for your help in advance.

Hello! We are working on uploading a new R tutorial very soon since the current one is outdated. In this case, you will want to put in a source parameter in get_transcriptomics. For example: transcript_py <- cc$get_transcriptomics('bcm')
