Loaded an empty dataset

Hi, thank you for the great work on this project!

I'm trying to run the following command:
python -m sample.generate --model_path ./save/humanml_trans_dec_512_bert/model000200000.pt --text_prompt "the person walked forward and is picking up his toolbox."

However, I get this error:
AssertionError: You loaded an empty dataset, it is probably because your data dir has only texts and no motions.
To train and evaluate MDM you should get the FULL data as described in the README file.

I've downloaded the dataset as mentioned in the README, but I'm not sure what exactly is missing. Could you please clarify what files are required in the data directory for sampling?

Thanks in advance for your help!

Start with the dataset and sampling instructions in the README, then trace the sample.generate entry point and the data-directory setup described by the error. Clarify which full dataset contents are required for sampling, including the motion data, and make the README answer the reported setup question.
