Hi,

I’ve been stuck on this for a while. I am getting the following error

```

```

I printed what is being sent to softmax and shapes of X and see the following

```
input shape (4,)
shape of X: (None, 5)
type of X: <class 'tensorflow.python.framework.ops.Tensor'>
```

I’ve gone through the a similar error and its suggested solution but no luck. Appreciate some guidance on this.
