| # This environment variable controls whether or not we print expected failure |
| # lists at the end of a test suite run. The intended usage looks like this: |
| # |
| # 1. Run `PYTORCH_COLLECT_EXPECT=1 python test/test_meta.py` on a CUDA build |
| # of PyTorch that has LAPACK/MAGMA installed. You can filter `-k test_meta` |
| # or `-k test_dispatch_meta` to only focus on one or another list |
| # 2. Given the printed skip/xfail list, add them to the corresponding lists; |
| # torch.* entries go in meta_function and aten.* entries go in meta_dispatch. |
| # If there are preexisting entries, you need to merge in the entries. |
| # |
| # This is somewhat manual but typically you shouldn't need to do this, unless |
| # you've made a major change (e.g., added a new dtype to PyTorch) and need to |
| # refresh the lists. If you want to do it from scratch, just clear out the |
| # preexisting lists before running. |
