Error using MONAI Label

[abhishekpatil32]

Hello all,

I am new to MONAI-label and would like to seek help regarding the same.
I am trying to run the segmentation model on my data.

I have uploaded my data in ImageTr folder with the labels in the subfolder "labels/final"
When I try to run the
monailabel start_server --app apps/radiology --studies dataset/ImageTr --conf models segmentation

I get an error

Using PYTHONPATH=/usr:

Extension horovod.torch has not been built: /usr/local/lib/python3.8/dist-packages/horovod/torch/mpi_lib/_mpi_lib.cpython-38-x86_64-linux-gnu.so not found
If this is not expected, reinstall Horovod with HOROVOD_WITH_PYTORCH=1 to debug the build error.
Warning! MPI libs are missing, but python applications are still avaiable.
