```python
class tensorplay.autograd.anomaly_mode.set_detect_anomaly(mode: bool, check_nan: bool = True)
```

Context-manager that sets the anomaly detection for the autograd engine on or off.

set_detect_anomaly will enable or disable the autograd anomaly detection
based on its argument mode.
It can be used as a context-manager or as a function.

See detect_anomaly above for details of the anomaly detection behaviour.

Parameters:

- mode ([bool](https://docs.python.org/3/builtins/functions.html#bool)) – Flag whether to enable anomaly detection (True), or disable (False).

- check_nan ([bool](https://docs.python.org/3/builtins/functions.html#bool)) – Flag whether to raise an error when the backward generate “nan”
