Help with Debugging TF Common tests
I am a TF2 Noob trying to get TFBart working. Most tests pass besides the ones relying on save_pretrained and pt conversion. Has anybody experienced the following issues?
```
test_tf_compile_model:
h5py/h5o.pyx:202: in h5py.h5o.link
...
RuntimeError: Unable to create link (name already exists)
```
Or
```
test_pt_tf_model_equivalence:
AttributeError: tf_bart_model_9.tf_bart_encoder_9.tf_shared_embeddings_9.weight not found in PyTorch model
```

`transformers-cli env`:

```bash
- `transformers` version: 3.0.0
- Platform: Darwin-19.4.0-x86_64-i386-64bit
- Python version: 3.7.5
- PyTorch version (GPU?): 1.5.0 (False)
- Tensorflow version (GPU?): 2.2.0 (False)
- Using GPU in script?: <fill in>
- Using distributed or parallel set-up in script?: <fill in>
```
