* init_optimizers accepts Dict, Sequence[Dict] and returns optimizer_frequencies. optimizer_frequencies was added as a member of Trainer. * Optimizer frequencies logic implemented in training_loop. Description added to configure_optimizers in LightningModule * optimizer frequencies tests added to test_gpu * Fixed formatting for merging PR #1269 * Apply suggestions from code review * Apply suggestions from code review Co-Authored-By: Asaf Manor <32155911+asafmanor@users.noreply.github.com> * Update trainer.py * Moving get_optimizers_iterable() outside. * Update note * Apply suggestions from code review * formatting * formatting * Update CHANGELOG.md * formatting * Update CHANGELOG.md Co-authored-by: Jirka Borovec <Borda@users.noreply.github.com>
PyTorch-Lightning Tests
Most PL tests train a full MNIST model under various trainer conditions (ddp, ddp2+amp, etc...). This provides testing for most combinations of important settings. The tests expect the model to perform to a reasonable degree of testing accuracy to pass.
Running tests
The automatic travis tests ONLY run CPU-based tests. Although these cover most of the use cases, run on a 2-GPU machine to validate the full test-suite.
To run all tests do the following:
git clone https://github.com/PyTorchLightning/pytorch-lightning
cd pytorch-lightning
# install AMP support
bash tests/install_AMP.sh
# install dev deps
pip install -r tests/requirements.txt
# run tests
py.test -v
To test models that require GPU make sure to run the above command on a GPU machine. The GPU machine must have:
- At least 2 GPUs.
- NVIDIA-apex installed.
Running Coverage
Make sure to run coverage on a GPU machine with at least 2 GPUs and NVIDIA apex installed.
cd pytorch-lightning
# generate coverage (coverage is also installed as part of dev dependencies under tests/requirements.txt)
coverage run --source pytorch_lightning -m py.test pytorch_lightning tests examples -v --doctest-modules
# print coverage stats
coverage report -m
# exporting results
