Install dependencies

1. Do the following before installing the dependencies found in requirements.txt file because of current challenges installing onnxruntime through pip install onnxruntime.

   • For MacOS users, a workaround is to first install onnxruntime dependency for chromadb using:

    conda install onnxruntime -c conda-forge

   See this thread for additonal help if needed.

   • For Windows users, follow the guide here to install the Microsoft C++ Build Tools. Be sure to follow through to the last step to set the enviroment variable path.

2. Now run this command to install dependenies in the requirements.txt file.

pip install -r requirements.txt
