Enable fast gradcheck for real inputs and outputs (#55237)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/55237
In this PR, we reenable fast-gradcheck and resolve misc issues that arise:
Before landing this PR, land #55182 so that slow tests are still being run periodically.
Bolded indicates the issue is handled in this PR, otherwise it is handled in a previous PR.
**Non-determinism issues**:
- ops that do not have deterministic implementation (as documented https://pytorch.org/docs/stable/generated/torch.use_deterministic_algorithms.html#torch.use_deterministic_algorithms)
- test_pad_cuda (replication_pad2d) (test_nn)
- interpolate (test_nn)
- cummin, cummax (scatter_add_cuda_kernel) (test_ops)
- test_fn_gradgrad_prod_cpu_float64 (test_ops)
Randomness:
- RRelu (new module tests) - we fix by using our own generator as to avoid messing with user RNG state (handled in #54480)
Numerical precision issues:
- jacobian mismatch: test_gelu (test_nn, float32, not able to replicate locally) - we fixed this by disabling for float32 (handled in previous PR)
- cholesky_solve (test_linalg): #56235 handled in previous PR
- **cumprod** (test_ops) - #56275 disabled fast gradcheck
Not yet replicated:
- test_relaxed_one_hot_categorical_2d (test_distributions)
Test Plan: Imported from OSS
