```python
tensorplay.func.batch_norm_without_running_stats(module: Module) → None
```

Drops the running statistics of one batch-normalization module.

Running statistics are updated in place on every forward pass.  Under a
transform that evaluates the module more than once – mapping over an
ensemble, or differentiating through it – those updates would be applied
repeatedly and in an order the caller never asked for, so the module is
switched to normalizing with the batch’s own statistics instead.
