SummarizationPipeline crashes

summarize = pipeline("summarization")
summarize("Sam Shleifer writes the best docstring examples in the whole world.")

Is this issue fixed in version 2.10.0?<|||||>@julien-c I still get the same error when doing

```
summarizer = pipeline('summarization')
```

and using it to summarize.

However the following explicitely works for me:

```
summarizer = pipeline('summarization', model='bart-large-cnn', tokenizer='bart-large-cnn')
```<|||||>Yeah that sounds like this issue. It will be fixed in the next release or you can build from source with
```bash
git clone [this repo]
pip install -e .

I have installed the package from GitHub repo but still have the same issue right now.<|||||>@khalilRhouma: It works for me at commit d976ef262e0b2c52363d201b2e14e5ecc42abbb3 , so you may need to `git pull` or some such. If that doesn't work I would love to see the output of 
```bash
transformers-cli env
```


<|||||>@sshleifer I get this error when I clone with that commit ID.
KeyError: "Unknown task summarization, available tasks are ['feature-extraction', 'sentiment-analysis', 'ner', 'question-answering', 'fill-mask']"
@dipanjanS  Would be great to know what configuration you used<|||||>current master should also work.<|||||>@sshleifer The kernel still crashes
Attaching the code.
```
from transformers import pipeline
import torch

!git clone https://github.com/huggingface/transformers.git
%cd transformers
`!pip` install -e ".[dev]"

#summarizer = pipeline("summarization")
summarizer = pipeline('summarization', model='facebook/bart-large-cnn', tokenizer='facebook/bart-large-cnn') ##Kernel dies after running this line
```

transformers version - 2.11.0
torch - 1.5.0<|||||>Can't replicate :(.
Can I see your `transformers-cli env` output?<|||||>How do I get that output? I'm running these on Jupyter without any virtual env<|||||>Got it.
- `transformers` version: 2.11.0
- Platform: Linux-4.14.181-108.257.amzn1.x86_64-x86_64-with-glibc2.9
- Python version: 3.6.10
- PyTorch version (GPU?): 1.5.0 (False)
- Tensorflow version (GPU?): 2.2.0 (False)
- Using GPU in script?: <No>
- Using distributed or parallel set-up in script?: <No><|||||>@sshleifer It works finally. There was a problem with GPU allocation. Thanks for your response.
