Error when attempting to Download Data

[Yeageon Song]

Dear OpenCap team!
I hope this post finds you well.
I am unable to download the data from these two sessions:

4a2994fc-5ed2-454e-872c-d662bdc7a581

04e2b3b2-915d-48ad-9933-a45e33932cbc

When I try to download the data I get 502 Bad Gateway Error. Please may you look into what the problem might be?
Thank you!

Hi Yeageon,

This happens when the dataset is too large--the connection with the server times out. We are about to launch a new way of downloading data over the web app that solves this problem (in the next 1-2 weeks).

In the meantime, you can reliably download data using this google collab notebook (https://github.com/stanfordnmbl/opencap ... load.ipynb), or just using a local python environment (https://github.com/stanfordnmbl/opencap ... ownload.py).

The new way of downloading data is live - please let us know if you still run into issues.

Antoine,
Is there a google colab notebook for reprocessing trials?

Thank you!

[Antoine Falisse]

For reprocessing data locally, you should download the opencap-core repository and follow the instructions to install all the packages: https://github.com/stanfordnmbl/opencap-core

You can then use this script to reprocess a trial: https://github.com/stanfordnmbl/opencap ... essions.py

Feel free to ask for any questions,

Antoine

Will this work locally on MacBook Pro? I'm familiar with python, but primarily utilize google colab. So while I'm following the instructions for doing it locally there's some differences since it's written for Windows 10 users.Thanks for all the feedback!

Hey, to run the code on your MacBook, you will need to find a way to run OpenPose on macOS. A brief google search suggests that some people have managed to do it. For the rest, our code should not be platform-specific. Let us know if you run into specific issues. Antoine

Hi everyone, i'm having a similar issue with 2 sessions.

When i try to download data (multiples times since the sessions), i get a infinite "download in progress", and so no Data.zip button.

I also want to know if there is a way to reprocess data online, in the cloud? That's simple curiosity.

Thanks you!

Vincent.

I'm having the same infinite 'download in progress issue with data I collected 19/6/2023

We'll look into the download problem. In the meantime, you can download data using the this notebook in google colab https://github.com/stanfordnmbl/opencap ... load.ipynb.

There's not a way to reprocess data through our web application. You can reprocess on a local machine with a decent GPU or a cloud instance (eg AWS EC2).
