## how to contribute
|
||
We have a fork of fastai to propose changes to fastai.text, with a branch for this project:
|
||
https://github.com/n-waves/fastai/tree/ulmfit_multilingual
|
||
|
||
Let us know that you want to start collaboration on fastai forum thread: [Multilingual ULMFIT](https://forums.fast.ai/t/multilingual-ulmfit/28117)
|
||
and you will get access to both repositories.
|
||
|
||
- Follow the [developer installation of fastai](https://github.com/fastai/fastai#developer-install)
|
||
- Add n-waves/fastai as additional remote as described here: https://help.github.com/articles/adding-a-remote/
|
||
|
||
Here is what I did:
|
||
```bash
|
||
$ cd fastai
|
||
$ git remote add n-waves https://github.com/n-waves/fastai.git
|
||
$ git remote -v
|
||
n-waves https://github.com/n-waves/fastai.git (fetch)
|
||
n-waves https://github.com/n-waves/fastai.git (push)
|
||
origin https://github.com/fastai/fastai.git (fetch)
|
||
origin https://github.com/fastai/fastai.git (push)
|
||
|
||
$ git fetch n-waves
|
||
$ git checkout ulmfit_multilingual
|
||
Branch 'ulmfit_multilingual' set up to track remote branch 'ulmfit_multilingual' from 'n-waves'.
|
||
Switched to a new branch 'ulmfit_multilingual'
|
||
|
||
$ git push --set-upstream n-waves ulmfit_multilingual # to automatically push ulmfit_multilingual branch to the n-waves repo
|
||
```
|
||
|
||
## Repo structure
|
||
|
||
- `fastai_contrib` -- anything that can be ported to fastai once we finish the project like: NLI models, Sentence Piece tok.,
|
||
- `ulmfit`
|
||
- `data` -- scripts to fetch and prepare data: wikipedia, xnli, classification data sets
|
||
- `lm` -- scripts to train language models
|
||
- `bilm` -- scripts to train biLM ELMo style, Bert style
|
||
- `class` -- scripts to test classifiers on multiple languages
|
||
- `xnli` -- scripts to test nli
|
||
|
||
|
||
## Running tests
|
||
|
||
To run the tests, the following data is necessary:
|
||
|
||
- wikitext-2 (prepared by `./prepare_wiki-en.sh`, along with wikitext-103)
|
||
- imdb (prepared by `./prepare_imdb.sh`)
|
||
|
||
then simply run tests, e.g. `pytest .`
