Reading sas7bdat large file using modin panda: FactoryDispatcher.read_sas() takes 1 positional argument but 2 were given

I want to read a large file in jupyter notebook. (can not read using pandas becuase of the memory constraints). The datafile requres over 35 GB memory but my space has only 20 GB. Therefore, I tried to use modin panda instead but occured error.

FactoryDispatcher.read_sas() takes 1 positional argument but 2 were given

## Reading sas7bdat
import modin.pandas as pd 
import numpy as np

cabd_2021 = pd.read_sas(
  '/xxx/xxx/xxx/xxxx/xxx/xxxx_010121.sas7bdat',
   format = "sas7bdat",
    encoding="latin-1"
 )
cabd

Returns ERROR
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

This is a Modin bug that was fixed in a pull request that has not made it into a release yet. You can install the latest version of Modin to get the fix, or you can wait for the next patch release of Modin. If you can't change your Modin version, you can read the dataframe into pandas with pandas.read_sas, then construct a Modin dataframe out of the resulting pandas dataframe.
