ImportError: cannot import name 'ESMForMaskedLM' from 'transformers'
### System Info

```shell
Hi, I am trying to use the esm model for protein sequence embeddings on Colab notebook:

1) I installed transformers with torch
!pip install transformers[torch]

2) Follow the example here: https://huggingface.co/facebook/esm-1b
from transformers import ESMForMaskedLM, ESMTokenizer
tokenizer = ESMTokenizer.from_pretrained("facebook/esm-1b", do_lower_case=False )
model = ESMForMaskedLM.from_pretrained("facebook/esm-1b")
sequence_Example = "QERLKSIVRILE"
encoded_input = tokenizer(sequence_Example, return_tensors='pt')
output = model(**encoded_input)

3) And got the import error:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-7-8f12e906d421> in <module>()
----> 1 from transformers import ESMForMaskedLM, ESMTokenizer
      2 tokenizer = ESMTokenizer.from_pretrained("facebook/esm-1b", do_lower_case=False )
      3 model = ESMForMaskedLM.from_pretrained("facebook/esm-1b")
      4 sequence_Example = "QERLKSIVRILE"
      5 encoded_input = tokenizer(sequence_Example, return_tensors='pt')

ImportError: cannot import name 'ESMForMaskedLM' from 'transformers' (/usr/local/lib/python3.7/dist-packages/transformers/__init__.py)

---------------------------------------------------------------------------
NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

Any idea how to solve this? Thanks in advance.

This doesn't work either. 
So why ESM can't be used with transformers even ESM2 has been published and ESM is just on the main page of this github.
