## Information

The problem arises when using:
* [ ] the official example scripts: (give details below)
I am attempting a fresh installation of transformers library, but after successfully completing the installation with pip, I am not able to run the test script: `python -c "from transformers import pipeline; print(pipeline('sentiment-analysis')('we love you'))"` 

Instead, I see the following output:

I have attempted uninstalling transformers and re-installing them, but I couldn't find any more information as to what is wrong, or how to go about fixing this issue I am seeing. The only suspicious behavior is that your tool for the environment detection above printed that I have torch installed without GPU, while in reality I have an installation of pytorch that works with gpu. Can you help?
Thanks in advance
Shushan
Hello! Could you show me the command you used to install `transformers`?  Thank you!<|||||>This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.

```<|||||>Yes, please rename your script. If you're doing `import transformers` from inside a script named `transformers.py`, the script will try to import itself.
