Hi Robert, If you do not want to install the library on every machine of the cluster, the Python dependency management API can be used to upload and use the required dependencies to cluster.
For this case, I recommend building a portable python environment that contains all the required dependencies. You can call `add_python_archives` to upload the environment to your and call `set_python_executable` to set the path of the python interpreter in your cluster. For more detailed information, you can refer to the following link.
