I'm studying chatbot with rasa.com, apixu, api.slack. But at the time want to training data, even out errors like this. Can you help me to solve this problem?

By the way I use anaconda3, python 3.6.

C:\Program Files\Anaconda3>python train_init.py

C:\Program Files\Anaconda3\lib\site-packages\h5py__init__.py:34: FutureWarning: Conversion of the second argument of issubdtype from float to np.floating is deprecated. In future, it will be treated as np.float64 == np.dtype(float).type.

from ._conv import register_converters as _register_converters

Using TensorFlow backend.

Traceback (most recent call last): File "train_init.py", line 17, in agent = Agent('weather_domain.yml', policies = [MemoizationPolicy(), KerasPolicy()])

File "C:\Program Files\Anaconda3\lib\site-packages\rasa_core\agent.py", line 42, in init

self.domain = self._create_domain(domain)

File "C:\Program Files\Anaconda3\lib\site-packages\rasa_core\agent.py", line 237, in _create_domain

return TemplateDomain.load(domain)

File "C:\Program Files\Anaconda3\lib\site-packages\rasa_core\domain.py", line 435, in load

slots = cls.collect_slots(data.get("slots", {}))

File "C:\Program Files\Anaconda3\lib\site-packages\rasa_core\domain.py", line 479, in collect_slots

slot_class = Slot.resolve_by_type(slot_dict[slot_name].get("type"))

AttributeError: 'NoneType' object has no attribute 'get'

In your case slot_dict[slot_name] is None. Make sure it is not None but some object. Here is the same error in a simplified way reflecting what happened in your scenario:

>>> d = {'key': None}
>>> d['key'].get('type')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
