Hi, i'm struggling to use pipeline module from transformers following the installation guide in this repo, maybe i'm doing something wrong and someone can help me. 

## Environment info
Tried to run 'transformers-cli env' and got same error i'm trying to report:

```

Another metric with the same name already exists.

```
- `transformers` version: 4.13.0.dev0 and tried 4.12.0 and same error
- Platform: Ubuntu 20.04.3 LTS
- Python version: Python 3.8.10
- PyTorch version (GPU?): none
- Tensorflow version (GPU?): tensorflow 2.6.1
- Using GPU in script?: No
- Using distributed or parallel set-up in script?: No

## Information

Model I am using (Bert, XLNet ...): I'm just importing pipeline from transformers.

The problem arises when using:
* [*] the official example scripts: (give details below)
* [ ] my own modified scripts: (give details below)

## To reproduce

Steps to reproduce the behavior:

I start from a clean pip environment
1. install tensorflow following installation page instructions
```
# Requires the latest pip
pip install --upgrade pip

# Current stable release for CPU and GPU
pip install tensorflow
```
2. install transformers following installation instruction:
`pip install transformers`
3. create a python script (test.py) and do: 
`from transformers import pipeline
`
4. run:
`python3 test.py`
5. i got the following error:
`Traceback (most recent call last):
  File "test.py", line 1, in <module>
    from transformers import pipeline
  File "<frozen importlib._bootstrap>", line 1039, in _handle_fromlist
  File "/home/ramirom/workspace/testTensor/env/lib/python3.8/site-packages/transformers/file_utils.py", line 2137, in __getattr__
    module = self._get_module(self._class_to_module[name])
  File "/home/ramirom/workspace/testTensor/env/lib/python3.8/site-packages/transformers/file_utils.py", line 2149, in _get_module
    raise RuntimeError(
RuntimeError: Failed to import transformers.pipelines because of the following error (look up to see its traceback):
Failed to import transformers.modeling_tf_utils because of the following error (look up to see its traceback):

## Expected behavior
I expect no error when just importing pipeline


Comments:
I've experienced the same problem, switching to an earlier version of tensorflow (2.5 instead of 2.6) seems to have solved it for me.
There seems to be some issue with 2.6 version right now according to this thread: #14265 

Just FYI: the underlying problem actually seems to come from keras 2.7 after some investigation: https://github.com/keras-team/keras/issues/15585

_meaning installing `keras==2.6.0` should solve the problem_

That did the trick, amazing. Thanks for the quick response!!

Hey @RamiroMoreira given the solution provided by @frgfm can we close this issue?

Yes, thank you!
