Error when reading the training data

[ngoductuanlhp]

Hi @mulns,

First, thank you for your excellent work. I am trying to reproduce the model using the CVO training data. However, after downloading the data from Baidu and attempting to read it with pickle.load() (since pyarrow.deserialize is deprecated), I encountered the error _pickle.UnpicklingError: invalid load key, '\x00'. Notably, I can successfully load the CVO-test data. Could you please help me verify the CVO-train data on the Baidu link?

Many thanks.

Can you try:

import pyarrow as pa

value = pa.deserialize(txn.get(key.encode()))

and tell me if it's resolved?
