torch.fx.experimental.symbolic_shapes.definitely_false¶
- torch.fx.experimental.symbolic_shapes.definitely_false(a)[source]¶
Returns True only if we can tell that a is False, possibly introducing a guard in the process. If a depends on some unbacked SymInt, we may return False even though there may exist a possible value of the SymInt that would cause the expression a to be False. See definitely_true for more usage guidance.
