For 4 epochs, I had a low error rate of 5.2%. However, after updating the learning rate while training, the error rate has gone up to 18.4%. Why does this happen?

\leftarrow Before updating the learning rate.

\leftarrow After updating the learning rate.

At first, the learning rate plot did not appear when I ran-

```
learn.recorder.plot()
```

I just received an empty plot.

Then, when I ran, as advised-

```
learn.lr_find(start_lr=1e-5, end_lr=1e-1)
learn.recorder.plot()
```

Then I got this-

So, when I ran the code with the learning rate specified, I got my errors increased.

Why does this happen? How to solve this problem?
