Local Development

Developing for Hub is as you expect for most Python packages.

Prepare Environment

It is highly recommended you use an environment manager when developing for any project, Hub is no exception. For more information on how conda works, please visit their website. You can create a new conda environment with the following (replace [version] with your version, must be greater than python3.6)

conda create -n hub python=[version]

Activate the environment

conda activate hub

Note: If you don’t like using conda, you can use venv instead.

Install Package

When installing the package, make sure you use the -e flag, this allows you to import hub from another project (with the same conda/venv environment) & make changes directly to the source with immediate updates.

git clone https://github.com/activeloopai/Hub
cd Hub
pip install -e .


Make sure that, after following the preceeding steps, you can now run this python script

from hub import Dataset

mnist = Dataset("activeloop/mnist")  # loading the MNIST data lazily
# saving time with *compute* to retrieve just the necessary data

If you receive the error

botocore.exceptions.ClientError: An error occurred (InvalidAccessKeyId) when calling the GetObject operation: The AWS Access Key Id you provided does not exist in our records.

Double check that you included aws_session_token within your ~/.aws/credentials profile. More information regarding AWS credentials can be found here.

If you are having a related problem, please read/comment on the reference issue or you can setup with docker.


Using the same development environment, you can locally build & contribute to the documentation (what you are on right now)


cd docs
pip install -r requirements.txt
