I'm using pandas to save a dataframe with 'xz' compression.

df.to_pickle("abc.pickle", compression="xz")

and the dotnet version threw an exception while loading it.

Unhandled exception. Razorvine.Pickle.InvalidOpcodeException: invalid pickle opcode: 253

Well, yeah, a compressed pickle isn't a pickle byte stream. You'll have to decompress it first.

You are right. Ok, Thanks.
