I am trying to use a package named Methylprep. It is using “append” function for dataframe, which has been removed since pandas 2.0.

Now the version of pandas installed in my pc is 2.2.2. And I am using jupyter notebook to process my scripts. Is there a way to allow me use specific version of pandas (maybe 1.8) in the script I am currently testing in jupyter notebook ?

Thank you very much !!

filepath = Path('test/')

data_containers = methylprep.run_pipeline(filepath, array_type=None, export=True, manifest_filepath=None, sample_sheet_filepath='test/MethylationEPIC_Sample_Sheet_B.csv')
