Python - Read msgpack file and store it to the Data Frame

def df_to_msgpack(df, filename):
df.to_msgpack(filename, default=decimal_default)

The function above stores the DF to messagepack file. Now, I want to read the file and store it in the DF for further calculation. How can it be done?

    with open(filename, 'rb') as data_file:
    data_loaded = msgpack.unpackb(data_file.read())

I tried the solution above and it didn't help. 

msgpack_read(filename)

The solution also only reads the file. Any solution?

Solution

  • You can use pandas.read_msgpack although it still is an experimental version in ver0.23.4.

    df = pd.read_msgpack(filename)
