"outer_lr" option doesn't work for HOW parameter in liana_tensor_c2c()

[JamesJDollar]

Hello,

I was using the liana_tensor_c2c function for my dataset, which worked when selecting "inner" or "outer" for the how parameter. However, "outer_lr" doesn't work for me.
Here is the command I used:

liana_tensor_c2c(sce = sce, score_col = 'LRscore', init = "random", runs = 10, rank = NULL, ='outer_lr', conda_env = NULL, use_available = FALSE)

And below is the error I get:

Building the tensor using LRscore... Error in py_call_impl(callable, call_args$unnamed, call_args$named) : ValueError: Not a valid input for parameter 'how' Run reticulate::py_last_error()` for details.
