Error in py_call_impl(callable, call_args$unnamed, call_args$named)

Help scvi-tools

Hi,
When I use scvi in R, errors occur when I set the parameters as follows; however, when I cancel these parameter settings and use the default parameters, the errors disappear. How can I resolve this issue?

model = scvi$model$SCVI(adata,

  •                     gene_likelihood = "nb",

  •                     n_latent = 50,

  •                     n_layers = 2)

Error in py_call_impl(callable, call_args$unnamed, call_args$named) :
TypeError: can’t multiply sequence by non-int of type ‘float’
Run reticulate::py_last_error() for details.
