报错OSError: [Errno 22] Invalid argument

Question

data_clean_1是xarray.dataset,我想给转化成dataframe，但是一直报错，这应该怎么解决啊？谢谢

for i in data_h_index:
    if select_time[i].split('-')[0] == '2019':
        data_clean_1 = data_ow_1.sel(time=select_time[i], longitude=select_lon[i], latitude=select_lat[i],method='nearest')
        DT_1 = data_clean_1.to_pandas()
        new_data_clean_1 = new_data_clean_1.append([DT_1])
