Verified Solution[pytorch/pytorch] torch.compile error in unit tests, but test passes when ran individually
Sponsored Content
### ROOT CAUSE
The test fails in the suite due to shared state or caching from previous tests affecting `torch.compile`, while running individually avoids this. The issue likely stems from PyTorch's compiler (Dynamo) retaining intermediate states across test runs, leading to inconsistent behavior.
### CODE FIX
```python
import torch
def test_function():
torch._dynamo.reset() # Reset compiler state before each test
# ... test code using torch.compile ...
```
This ensures the compiler starts fresh for each test. Alternatively, explicitly disable Dynamo for the test:
```python
import torch
def test_function():
with torch._dynamo.config.persistent_cache(False):
# ... test code using torch.compile ...
```
Both solutions address the shared state issue in the test suite.
