Sentencepiece dependency causing docker build to fail
## Environment info

- `transformers` version:3.4.0
- Platform:Ubuntu 18.04
- Python version: 3.7
- PyTorch version (GPU?): 1.7.0 no gpu
- Tensorflow version (GPU?): N/A
- Using GPU in script?: no
- Using distributed or parallel set-up in script?: no


## Information

Question answering pipelines is the feature I am using. There is a problem with the sentencepiece dependency of transformers. It cannot find the correct package when installing and causing the build process to fail

The problem arises when using:
Downloading the transformers library onto a docker container running ubuntu.

The tasks I am working on is:
Uploadding a transformers script to AWS fargate

## To reproduce

Steps to reproduce the behavior:

1. Create a project
2. Try to create docker container using dockerfile attached below

I have attached the relevant parts of my dockerfile below
Dockerfile

```
FROM ubuntu:18.04

RUN mkdir /usr/app
WORKDIR /usr/app

# Add and install Python modules
COPY requirements.txt ./
RUN apt-get update
RUN apt-get -y install python3
RUN apt-get -y install python3-pip
RUN pip3 install virtualenv
ENV VIRTUAL_ENV=/venv
RUN virtualenv venv -p python3
ENV PATH="VIRTUAL_ENV/bin:$PATH"

RUN pip3 install transformers[torch]
RUN pip3 install torch==1.7.0+cpu torchvision==0.8.1+cpu torchaudio==0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
RUN pip3 install -r requirements.txt

# Bundle app source
COPY . ./
# Expose
EXPOSE 6000
# Run
CMD ["python", "app.py"]

```
This is the stack trace that comes back from running and trying to build using this dockerfile

## Expected behavior

I expect transformers to be downloaded and allow me to access it from the docker container.

This will be fixed when #8073 is merged.<|||||>Is there any help in terms of what version to pin to in order to avoid this? This is currently a huge blocker on my end.<|||||>On the sentencepiece side I don’t know (you can open an issue on their side to ask) but on the `transformers` side we are actively working on removing the hard dependency on sentencepiece and we estimate we should have a new release removing this dependency around the end of next week.

Cc @n1t0 and @Narsil whose work on `tokenizers` is essential to unlock this.<|||||>Great! Thanks for the info!<|||||>This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.
