Is it possible to use string data to train a NN? I am trying to use 'labels' obtained from a previous network that labels an image. I want to use this data to predict the image. When I am using th is data it is stating it has to be a numerical/logical value.

Neural networks can only take numbers as input, so you have to convert your text features to numerical features. If the 'labels' are categorical you could for example use one-hot encoding. There are also more advanced text embeddings where semantically similar texts are encoded into similar (numerical) vector representations (for example word2vec).

To add to Olof's answer, the categorical type allows you to efficiently represent a finite set of discrete categories that you might otherwise represent with strings.
Take a look at the following example from the documentation demonstrating how to make predictions using categorical features.
