Loaded an empty dataset

[Leocoding0971]

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!

@Leocoding0971 hello i finally solve this problem, i think you download the dataset through the author's link( first methodDownload HumanML3D , but the author's dataset not include the [texts] folder, i share this folder in this link, just download it and put it in /MDM/dataset/HumanML3D/ , and you will solve this problem : )

And the link you give still requires a Request from the owner so I will wait and see if it works

Hi, you can download the [texts] file from "kaggle.com", it provides HumanML3D dataset which including a text file.

I got the same problem a while ago. I think the problem was that the "texts" was in a zip file
