pandas.read_feather got an unexpected argument nthreads

I tried saving a dataframe to feather format but while loading back I got the error

os.makedirs('tmp', exist_ok=True)
df_hist.to_feather('tmp/historical-raw')

Here's the loading back into the dataset

df_hist= pd.read_feather('tmp/historical-raw')

which gives the following error

read_feather() got an unexpected keyword argument 'nthreads'

Thanks in advance

Solution

  • Try replacing below line 

    df_hist= pd.read_feather('tmp/historical-raw')

    with

    import feather
df_hist=feather.read_dataframe('tmp/historical-raw')

    above change worked for me
