AttributeError: module 'tensorflow' has no attribute 'Tensor' when using documentation code (Tokenizer.batch_decode)

### Information



I was referring to the documentation on huggingface to run the facebook OPT model here:

https://huggingface.co/docs/transformers/main/en/model_doc/opt#transformers.OPTForCausalLM

And I've received the following error on my Windows 10 machine in VScode.

```
Traceback (most recent call last):
  File "c:/Users/Admin/Desktop/Projects/NLP_Cron/script_chat.py", line 11, in <module>
    print(tokenizer.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0])

    token_ids = to_py_obj(token_ids)
  File "C:\Users\Admin\Desktop\Projects\NLP_Cron\cronenv\lib\site-packages\transformers\utils\generic.py", line 160, in to_py_obj
    elif is_tf_tensor(obj):
  File "C:\Users\Admin\Desktop\Projects\NLP_Cron\cronenv\lib\site-packages\transformers\utils\generic.py", line 136, in is_tf_tensor
    return False if not is_tf_available() else _is_tensorflow(x)
  File "C:\Users\Admin\Desktop\Projects\NLP_Cron\cronenv\lib\site-packages\transformers\utils\generic.py", line 129, in _is_tensorflow
    return isinstance(x, tf.Tensor)
AttributeError: module 'tensorflow' has no attribute 'Tensor'
```

I first thought it was specific to this model, But I'm facing the same issue on other models.
I have tried uninstalling TensorFlow and reinstalling it.

I have upgraded "transformers" library as well. But to no avail. This seems to be a recent problem.

The virtual environment I'm using says I have these versions of tensorflow and transformers.

- transformers                  4.25.1
- tensorflow                    2.11.0

### Reproduction

Steps to reproduce the behaviour:

1. Go to https://huggingface.co/docs/transformers/main/en/model_doc/opt#transformers.tensorflow
2.  Run the example snippet consisting of this code

```
from transformers import GPT2Tokenizer, OPTForCausalLM

model = OPTForCausalLM.from_pretrained("facebook/opt-350m")
tokenizer = GPT2Tokenizer.from_pretrained("facebook/opt-350m")

prompt = "Hey, are you consciours? Can you talk to me?"
inputs = tokenizer(prompt, return_tensors="pt")

# Generate
generate_ids = model.generate(inputs.input_ids, max_length=30)
print(tokenizer.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0])
```

Assuming required libraries are installed error message shows up.

### Expected behavior

Expected the output as per shown in documentation.
Hi, @gaurav-95 
Please run `transformers-cli env` in terminal and share the full system info so it's easier to reproduce the error.<|||||>transformers-cli env gives me this. 

```

Could you elaborate on what system info do you need?
Im running on an Intel(R) Core(TM) i5-1035G1 CPU @ 1.00GHz   1.19 GHz
20.0 GB (19.8 GB usable) RAM

No dedicated gpu in machine. My virtualenvironment is called "cronenv"

Update:  I was able to run the same code on a google colab notebook, seems like a problem with my environment.<|||||>Hi, @gaurav-95 
Actually if you run the above code it should output something like this, 
- `transformers` version: 4.25.1
- Platform: Linux-5.15.0-58-generic-x86_64-with-glibc2.35
- Python version: 3.9.15
- Huggingface_hub version: 0.11.1
- PyTorch version (GPU?): 1.13.1 (True)
- Tensorflow version (GPU?): 2.10.0 (True)
- Flax version (CPU?/GPU?/TPU?): not installed (NA)
- Jax version: not installed
- JaxLib version: not installed
- Using GPU in script?: <fill in>
- Using distributed or parallel set-up in script?: <fill in>

Since you are not getting it could you please check your transformers installation? (just run `import transformers` and check if it successfully imports or gives an error) 
 
<|||||>Thanks for getting back and hinting towards the problem. I can confirm there was something wrong with my python installation. 

Steps that resolved it for me.

1. I made a requirements file of the existing install
2. I deleted the existing virtual environment.
3. Re-installed python.
4. Re-installed dependencies from saved requirements file.
5. Ran code and it works now!<|||||>> Thanks for getting back and hinting towards the problem. I can confirm there was something wrong with my python installation.

LOL, I got the same thing happen to me as well I think??? Ill give this a try :) BTW how did you delete the env?
