TypeError: ‘TrainingData’ object is not iterable

I am getting the above error when I am doing this in custom component: def train(self, training\_data, cfg, \*\*kwargs): print(“I am in train”) for item in training\_data: print(item)

Hi there @prithvini04! Your `training_data` parameter is not a list, but rather a `TrainingData` class of its own found in `rasa/nlu/training_data/training_data.py`. It’s always good to check the types of the parameters you are using and check out the class in the source code if you run into issues. I believe what you want is

```auto
for item in training_data.training_examples: 
    print(item)
```

hi, Yes I could now able to access from training\_data.training\_examples.

Couldn’t find the rasa/nlu/training\_data/training\_data.py in my local system. RASA is installed. where can I find it.

I’m not sure, it depends on your system. If you installed it in a virtual environment, it’s probably in there. You’d have to do a search on your machine for `training_data.py`.
