You can get all the necessary dependencies by simply installing fastai v1:
conda install -c fastai -c pytorch fastai. Or alternatively you can automatically install the dependencies into a new environment:
git clone https://github.com/fastai/fastai2 cd fastai2 conda env create -f environment.yml source activate fastai2
Then, you can install fastai v2 with pip:
pip install fastai2.
Or you can use an editable install (which is probably the best approach at the moment, since fastai v2 is under heavy development):
git clone https://github.com/fastai/fastai2 cd fastai2 pip install -e ".[dev]"
You should also use an editable install of
fastcore to go with it.
If you want to browse the notebooks and build the library from them you will need nbdev:
pip install nbdev
fastai2.medical.imaging you'll also need to:
conda install pyarrow pip install pydicom kornia opencv-python scikit-image
To run the tests in parallel, launch:
After you clone this repository, please run
nbdev_install_git_hooks in your terminal. This sets up git hooks, which clean up the notebooks to remove the extraneous stuff stored in the notebooks (e.g. which cells you ran) which causes unnecessary merge conflicts.
Before submitting a PR, check that the local library and notebooks match. The script
nbdev_diff_nbs can let you know if there is a difference between the local library and the notebooks.
