Having installed transformers and trying:

import transformers  
import librosa  
import soundfile as sf  
import torch  
from transformers import Wav2Vec2ForCTC  
from transformers import Wav2Vec2Tokenizer

#load model and tokenizer  
tokenizer = Wav2Vec2Tokenizer.from\_pretrained(“facebook/wav2vec2-base-960h”)  
model = Wav2Vec2ForCTC.from\_pretrained(“facebook/wav2vec2-base-960h”)

I get:

ImportError Traceback (most recent call last)  
 in   
3 import soundfile as sf  
4 import torch  
----\> 5 from transformers import Wav2Vec2ForCTC  
6 from transformers import Wav2Vec2Tokenizer  
7

ImportError: cannot import name ‘Wav2Vec2ForCTC’ from ‘transformers’ (c:\python\python37\lib\site-packages\transformers\__init_\_.py)

How I install/get Wav2Vec2ForCTC and Wav2Vec2Tokenizer ???

This probably means you don’t have the latest version. You should check your version of Transformers with

```auto
import transformers
print(transformers. __version__ )

```

and if you don’t see at least 4.3.0, you will need to upgrade your install.

I have the same issue with Windows 10.

> pip install transformers[torch]==4.3

> import transformers  
> print(transformers. **version** )  
> 4.3.0  
> from transformers import Wav2Vec2Tokenizer, Wav2Vec2ForCTC  
> Traceback (most recent call last):  
> File “”, line 1, in   
> ImportError: cannot import name ‘Wav2Vec2ForCTC’

I had the same issue. I upgraded the transformers version from 4.3.0 to 4.3.2 with  
`pip install transformers==4.3.2`  
and that worked for me. Also, upgrade your PyTorch to its latest version 1.7 with  
`pip install torch==1.7`  
that avoids error while loading pre-trained weights in the next step.

use " from transformers import \*" instead of “from transformers import Wav2Vec2Tokenizer, Wav2Vec2ForCTC”
