outsym = symtab.get_var(model._output_layers[0].name + ':0')
must be
outsym = symtab.get_var(model.layers[-1].name + ':0')

Which backend are you using for Keras? As I wrote in the link, TVM supports Keras with the tensorflow backend only for now. See also #1392.

Anyway, I think further discussion should be moved to https://discuss.tvm.ai/ .

This is mainly due to keras versions, if you update to latest keras version it should be fine

I've got similar error:
AttributeError: 'Model' object has no attribute '_network_nodes'
which was due to Keras version conflict, choosing version 2.3 resolved the issue.
