#### Accumulated gradients
|
||||
Accumulated gradients runs K small batches of size N before doing a backwards pass. The effect is a large effective batch size of size KxN.
|
||||
|
||||
``` {.python}
|
||||
# default 1 (ie: no accumulated grads)
|
||||
trainer = Trainer(accumulate_grad_batches=1)
|
||||
```
|
||||

|
||||
#### Check GPU usage
|
||||
Lightning automatically logs gpu usage to the test tube logs. It'll only do it at the metric logging interval, so it doesn't slow down training.

||||

|
||||
#### Check which gradients are nan
|
||||
This option prints a list of tensors with nan gradients.
|
||||
``` {.python}
|
||||
trainer = Trainer(check_grad_nans=False)
|

```

#### Check validation every n epochs
|
||||
If you have a small dataset you might want to check validation every n epochs
|
||||
``` {.python}
|
||||
trainer = Trainer(check_val_every_n_epoch=1)
|
||||
```
|
||||
|
||||

|
||||
#### Display metrics in progress bar
|
||||
``` {.python}

trainer = Trainer(progress_bar=True)
