Failed to run minimal code example

I tried to run the minimal code example with this configuration file but failed. It reported this error:

Traceback (most recent call last):
  File "code2seq_example.py", line 34, in <module>
    train(__config)
  File "code2seq_example.py", line 24, in train

omegaconf.errors.ConfigAttributeError: Missing key hyper_parameters
    full_key: hyper_parameters
    object_type=dict

What I did:

1. Copy the code example to a .py file and this configutation file to a .yaml file
2. Download the data from the url https://s3.eu-west-1.amazonaws.com/datasets.ml.labs.aws.intellij.net/java-paths-methods/java-small.tar.gz in the configuration file and compress it.
3. Change the first line of the .yaml file (data_folder) to the location of data.
4. Run this script python xxx.py xxx.yaml

I noticed that this error was related to "yaml" but I don't know where exactly the problem lies. I want to run a demo of code2seq model by this library. Thank you!

Hello. I tried demo too. but cause same error.
The procedure was almost the same as above.
You have a solution, I'd appreciate it if you could let me know.

Hi!
Sorry for the long response, in Russia, we had long New Year holidays :)

Thanks for pointing out this error. README was a little bit outdated. As you can see in config examples, the section with hyper-parameters was renamed to train to simplify usage.

I update the code example and also provide information about data mining tools and available checkpoints. If you still have trouble with usage, please let me know. I would love to help you!
