FileNotFoundError when python runs setup.py for sentencepiece
I am Running Python 3.7, Tensorflow 2.1, Buster

Model I am using (Bert, XLNet ...):  Would be using gpt-2 if I can install it...

Language I am using the model on is English

The problem arises when installing using

    pip install transformers

## To reproduce

Steps to reproduce the behavior:

Run on a Raspberry Pi 4B (4Gig) running Python 3.7, Tensorflow 2.1 and Buster

1.  pip install transformers

Wait for other downloads and installing to complete and this will eventually arise:

```

SO I TRIED download the wheel file from https://github.com/google/sentencepiece/releases for my python version and installing it with pip install sentencepiece-xxx-cpxx-xx.whl

However I see only Mac, x86, and "manylinux" wheels but the manylinux wheels specifically reference iOS or x86, nothing I can see for Arm Core 71 (linux_armv7l).

Also tried a straight install on sentencepiece with identical failure::

```
$ pip install sentencepiece

```


## Expected behavior

I was expecting installation to complete successfully.

## Environment info

$ python transformers-cli env
python: can't open file 'transformers-cli': [Errno 2] No such file or directory

This makes sense since transformers never finishes installing
     
- `transformers` version: Newest available with pip install
- Platform:  Raspbian Buster
- Python version:  3.7.3
- PyTorch version (GPU?):
- Tensorflow version (GPU?):  2.1 cpu
- Using GPU in script?:
- Using distributed or parallel set-up in script?:


Thanks for your assistance.


Sounds like a [sentencepiece](https://github.com/google/sentencepiece) issue?<|||||>I have an inquiry there as well since just a straight install of sentencepiece gives same results - I was just hoping there might be a way of using the HuggingFace Transformers without sentencepiece (although the name sentencepiece suggests to me that it may perform some critical functions...)  something like "pip install transformers --skip sentencepiece" ? :)
<|||||>@DaveXanatos Even I faced same issues. Issue seems to be with pip package of sentencepiece. I have opened an issue with them.

As a word around, I installed sentence piece from conda and it worked. After installing this you can install transformer.

`conda install -c powerai sentencepiece`
<|||||>Be wary of using conda and pip at the same time, if you don't know _exactly_ what you are doing, this will lead to unexpected complications.

SentencePiece is required for most recent models, so it is a hard dependency. I advise you to just wait until this is solved in the sentencepiece library, or download and install an earlier version of their library, e.g. https://github.com/google/sentencepiece/releases/tag/v0.1.84<|||||>@tkhan3 Thanks for the conda possibility, I will look into that in the interim.

@BramVanroy I have heard this before and a couple of years ago I completely hosed my build doing just this :)  Where would you suggest, as the most direct route to understanding exactly the differences between pip installs and conda installs in terms of paths, dependencies, etc., such that I could conda install with confidence a package in an otherwise pip installed environment?<|||||>I'm afraid I cannot help with that. I stay away from conda as much as I can. Pipenv is my main driver, falling back to an environment's pip where necessary.<|||||>@BramVanroy I'm with you on that from my experience, although I know some folks swear by it...  thanks for the warning.  I'll probably flash a backup image and then go and play with the possibilities and see if I can get it to work... I can always reflash back to the backup if I break everything again.  If I have success I'll let you know what I found.<|||||>Closing this. I propose that the discussion is moved to the sentencepiece library. https://github.com/google/sentencepiece/issues/452<|||||>I got a similar issue.
When I install sentence-transformers on Linux by python, I got an error message: 

ERROR: Could not find a version that satisfies the requirement transformers>=3.0.2 (from sentence-transformers) (fr
om versions: 0.1, 2.0.0, 2.1.0, 2.1.1, 2.2.0, 2.2.1, 2.2.2, 2.3.0, 2.4.0, 2.4.1, 2.5.0, 2.5.1)
ERROR: No matching distribution found for transformers>=3.0.2 (from sentence-transformers)

system: Linux 4.9.0-12-amd64 #1 SMP Debian 4.9.210-1+deb9u1 (2020-06-07) x86_64 on GCP VM instance.
Is there any suggestion?
<|||||>I had the same issue but on Unbuntu 20.04.1.
My problem was that i used a pip version to old to install sentencepiece, as it requires pip>=19.3.  (https://github.com/google/sentencepiece/issues/572#issuecomment-716890916)
So my solution was to upgrade my pip installation to 20.2.4
$ pip install --upgrade pip

Similar issues has been discussed here https://github.com/google/sentencepiece/issues/572

Hope it helps
