Hi, @Chenfei-Kang.

I'm sorry, but I'm not able to reproduce your bug:

from datasets import load_dataset

ds = load_dataset("glue", 'cola')
ds

DatasetDict({
    train: Dataset({
        features: ['sentence', 'label', 'idx'],
        num_rows: 8551
    })
    validation: Dataset({
        features: ['sentence', 'label', 'idx'],
        num_rows: 1043
    })
    test: Dataset({
        features: ['sentence', 'label', 'idx'],
        num_rows: 1063
    })
})

Could you please give more details and environment info (platform, PyArrow version)?

• For the platform, we need to know the operating system of your machine. Could you please run the command datasets-cli env and copy-and-paste its output below?
• In relation with the error, you just gave us the error type and message (TypeError: 'NoneType' object is not callable). Could you please copy-paste the complete stack trace, so that we know exactly which part of the code threw the error?

1. For the platform, here are the output:
   - datasets` version: 1.11.0

   - Python version: 3.7.10
   - PyArrow version: 5.0.0
2. For the code and error：

   from datasets import load_dataset, load_metric
   dataset = load_dataset("glue", "cola")

   Traceback (most recent call last):
   ....

   Thank you!

For that environment, I am sorry but I can't reproduce the bug: I can load the dataset without any problem.

[albertvillanova]

One naive question: do you have internet access from the machine where you execute the code?

[Chenfei-Kang]

For that environment, I am sorry but I can't reproduce the bug: I can load the dataset without any problem.

But I can download other task dataset such as dataset = load_dataset('squad'). I don't know what went wrong. Thank you so much!

Hi,friends. I meet the same problem. Do you have a way to fix this? Thanks!

[OptNuo]

I'm getting the same error. Have you solved the problem? Please tell me how to fix it

[rippleD030]

same error, fix by Downgrade the datasets version to 2.16.0.

[Doby-Xu]

Similar error when trying to download another dataset with 2.16.0, but 2.10.0 works

[Ki-Seki]

Same issue in v3.1.0; resolved by downgrading to v2.21.0.

[no-con]

same error, using the lower version 2.16.0 works
