Before fixing:

After fixing:

test_fpbase.py

Change the code: dfs = self.df.astype(pd.SparseDtype("int", np.nan)) dfs = self.df.astype(pd.SparseDtype("int", 0)) because the na_value of the "int" variable in the pd.SparseDtype() function must be 0. You can look at the document

Change the compare_dataframes() function: assert_array_equal() function was not working correctly. To fix this error, I replaced it with the compare_dataframes() function I wrote in "test_hmine.py".

Thanks so much for the update, the assert_array_equal() function was not working correctly issue was a sneaky one.
