### Who can help

tokenizer: @LysandreJik 

## Information

Model I am using (Bert, XLNet ...): GPT2

The problem arises when using:

* [ ] my own modified scripts: (give details below) 
* [ ] my own task or dataset: (give details below) text generation

After upgrade to 4.6.1 (same error in 4.6.0), I have an error when I load tokenizer.

### What I have tried
I searched for a similar issue and thought that this is a possible duplicate of [this issue](https://github.com/huggingface/transformers/issues/11713), but there was no change after I apply the solution.

I uninstalled transformers and tokenizers package, reinstall those, and still there is the same issue.

## To reproduce

Steps to reproduce the behavior:

1. Import tokenizer (like below)

```
from transformers import (PreTrainedTokenizerFast,
                          GPT2Tokenizer,)

```

## Expected behavior

Just work like before!

Hello, the error is pretty straightforward: your Python environment has the wrong `tokenizers` version.

I would suggest you reinstall tokenizers *while making sure you are in the same environment as your python runtime*: `pip install -U tokenizers`<|||||>`pip install -U tokenizers` does not solve the problem. And after several trials, I could not help recreating the docker container to make this work. I guess It was due to creating a new conda environment inside of a docker container. Thank you for your reply! Will close the issue. <|||||>I have this identical issue.  I am running python under WSL2, which is a docker container, I gather.
<|||||>I'm having the same issue, using conda inside docker since I need to create a jupyter notebook server<|||||>I have the same problem.

I fixed it by update python's  version  from 3.6 to 3.9. <|||||>I try to run `pip uninstall tokenizers` for 2 times, and solved.

<|||||>Re-install transformers with a proper version will be ok. I solve it by the command: `pip install transformers==4.11.3`.<|||||>it works on python 3.8 when transformers==4.11.3.
So using `pip install transformers==4.11.3` for the proper installation version.

3.8 and above will need to upgrade the transformers to 4.2x.xx
