Having a problem getting the sizings correct. Have been able to get into row, but not a column using the *tf.one_hot(indices=label, depth=4, axis=0), [-1] )*. Here is the result and error I am getting using this form. I would appreciate any hints on where to look fix this.

It instructions it has been specified we have to consider last elements. In a list we move from left ryt we use 0- length of list but if we traverse ryt to left we start from -1. Go through the instructions again u will get the idea.

TF.one hot take two argument which are

- List which has to be one encoded
- Depth which is number of classses

It looks like your result is a 1D tensor, but it should be a 2D tensor with one column. The instructions tell you to use *tf.reshape* on the output of *tf.one_hot* to get the result into the shape that they specify.
