Is there a way to change encoding py_load_object()?

[maksymiuks]

Hello.

I have a problem with loading pickle file created under python 2.7. When I try to load it via py_load_object() in env with python 3.7 i get error:

Error in py_call_impl(callable, dots$args, dots$keywords) : 
  UnicodeDecodeError: 'ascii' codec can't decode byte 0xcb in position 0: ordinal not in range(128)

is there a way to overcome it? (Other than using python 2.7 env)

The py_load_object() function is pretty simple:

> reticulate:::py_load_object
function(filename, pickle = "pickle") {
  builtins <- import_builtins()
  pickle <- import(pickle)
  handle <- builtins$open(filename, "rb")
  on.exit(handle$close(), add = TRUE)
  pickle$load(handle)
}

Perhaps we could augment the function to accept other arguments that can be passed down to pickle$load().
