Hello, I am downloading a model via Dropbox url and saving the data as a system string.  In order to load the model into Pytorch I have to convert the data from string to byte data.  When I use .encode() with ‘UTF-8’ codec to convert the string data to byte data and try to load it into BytesIO I get UnpicklingError: invalid load key, ‘<’
I wish I could just use Python request and use the method .content to get the raw byte info but I am stuck with string data on the platform I am using.
Any other ideas on how to convert string data to byte?
data_str = self.Download("https://www.dropbox.com/s/examplepath/checkpoint.pth?dl=1")

data_byte = data_str.encode()

self.agent.local.load_state_dict(torch.load(BytesIO(data_byte), map_location=lambda storage, loc: storage))


UnpicklingError: invalid load key, ‘<’
