The text generation example outputs an error related to print_tree()

[atantos]

When trying to download the huggingface model with const model = hgf"gpt2:lmheadmodel" of the text generation example, I get the following error. As a result, I cannot run the rest of the example file that follows.

Thanks for your work!

I downgraded AbstractTrees.jl to 0.3 and the issue is resolved.
