OSError in linux server
### System Info

Python 3.8.10

version of transformers == 4.0.1

linux server


### Who can help?

@patil-suraj

Hi. I'm fine-tuning TrOCR in Farsi.

### Information

- [ ] The official example scripts
- [X] My own modified scripts

### Tasks

- [ ] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
- [X] My own task or dataset (give details below)

### Reproduction

tokenizer xlm-roberta-large
model: 
`model = VisionEncoderDecoderModel.from_encoder_decoder_pretrained("google/vit-base-patch16-224-in21k", 'facebook/mbart-large-50', from_tf=True)`

### Expected behavior

I expect it to run and train the model as it does in colab, but it gives me this error:

> OSError: Unable to load weights from pytorch checkpoint file for '/root/.cache/huggingface/transformers/d01bfc4a52063e6f2cc1bc7063192e012043a7c6d8e75981bb6afbb9dc911001.e4710baf72bd00d091aab2ae692d487c057734cf044ba421696823447b95521e' at '/root/.cache/huggingface/transformers/d01bfc4a52063e6f2cc1bc7063192e012043a7c6d8e75981bb6afbb9dc911001.e4710baf72bd00d091aab2ae692d487c057734cf044ba421696823447b95521e'. If you tried to load a PyTorch model from a TF 2.0 checkpoint, please set from_tf=True.
