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

[renatochacon]

Hello. I was able to use 'ludwig experiment' on the titanic's datasets on kaggle, just as described here https://uber.github.io/ludwig/examples/ using the suggested yaml file.

I also tried to use it to train a dataset, but got this on terminal:

$ ludwig train --data_csv train.csv --model_definition modelo.yaml

Please use the latest code from master and try again.
Uninstall Ludwig, then:
pip install http://github.com/uber/ludwig/zipball/master

Thank you. I'd like to know one more thing, please:

I was able to work on the train.csv which contais all columns, including features (input variables) and target (output variable). But how do I use ludwig to predict on datasets like the one from test.csv which doesn't contain the target column 'Survived'?

[w4nderlust]

Read the docs, in the predict section of the user guide. There's a parameter --only_predict.

@w4nderlust I think in the last version of ludwig (0.4) this is happening again.
I get as well the mentioned error message, i.e.

$ python3 simple_model_training.py
Traceback (most recent call last):
  File "simple_model_training.py", line 25, in <module>
    logging_level=logging.INFO)
  File "lib/python3.7/site-packages/ludwig/api.py", line 193, in __init__
    self.backend = initialize_backend(backend or config.get('backend'))
AttributeError: 'str' object has no attribute 'get'

Could you maybe double check?
If so, should we reopen this issue, or create a new one?
Many thanks and best regards.

@vreyespue it's a different error.
Can you please open a separate issue about it with instructions on how to reproduce it?
I run the simple_model_training.py in the examples/titanic, which I believe is what you were running, and it works fine.

[vreyespue]

Hi @w4nderlust I got this issue both in macos and linux, simply by doing a pip install ludwig and executing simple_model_training.py in the examples/titanic folder. Actually I think it is because here we call the api with config as str (i.e. file path), and in the api we try to get the backend from the string, which results in an error. I opened the PR #1213 to resolve the issue. Using the previously validated self.config works for me perfectly, and should work as well in all setups. Many thanks and best regards.

[w4nderlust]

The PR #1213 was merged.

@w4nderlust Hi Pierre, I'm getting the same issue as vreyespue. Config file in same directory as python file. Replacing the config YAML with a python dictionary and works as expected. Any thoughts?

@Judy-Bloom the issue has been solved but we haven't released a new version yet. You can install Ludwig by cloning the tf-legacy branch in the meantime. We are going to release a v0.4.1 this week anyway ;)

[Judy-Bloom]

Thanks man :) looking forward to it.
