Support bytes python type
Currently there's no way to send bytes directly from one algorithm to another.
The current "workaround" is to build the bytes output then use base64 encoding, use a string based type to write the data to the output and on the other end load it back from string.
Example of working code:
Output:
obj = dict(field1=data.value*2, field2=data.value)
dumped = pickle.dumps(obj) # binary
encoded = base64.b64encode(dumped) # base64 bytes
string = encoded.decode("ascii") # "stringified"
outputs["out_data"].write({"value": string})
WARNING Do not call str(encoded), it won't be a "real string":
example = b"whatever"
example_str = str(example)
example_str
# output is "b'whatever'"
Input:
in_data = inputs["in_data"].data # string data
decoded = base64.b64decode(in_data.value) # decode to bytes
obj = pickle.loads(decoded) # obj is a dict and can be read
This issue tracks the implementation of the support for the python bytes type.
