Who can help

Information

I’m sorry for not being able to give more information about this, since I don’t directly works with the model. I believe the model is bert-base-multilingual-cased. I’m trying to create a chat bot with Rasa.

To reproduce

Steps to reproduce the behavior: Run the chat bot, either use rasa shell or rasa run --enable-api and curl to chat with the bot.

AttributeError: 'tuple' object has no attribute 'as_list'

Line 1831 of transformers/modeling_tf_utils.py:

static = tensor.shape.as_list()

After printing out stuff in transformers/modeling_tf_utils.py, I found out that sometime tensor is a numpy array, therefore tensor.shape is a tuple and indeed doesn’t have as_list.

Proposed fix:

    static = tensor.shape
    if type(static) == tuple:
        static = list(static)
    else:
        static = static.as_list()

Expected behavior

No error.

Sorry but I have a potato computer and I’m too lazy for the full PR procedure 😄

Nice catch, do you want to open a PR with the fix?
