Error in running examples.py for habitat-sim version

[LaughBuddha]

Hi,

After installing the specified version of habitat-sim, I run the following test script to test the installation. python examples/example.py --scene /path/to/data/scene_datasets/habitat-test-scenes/skokloster-castle.glb

But i'm getting the below error message. ImportError: ImportError: /mnt/beegfs/home/sidgoel/multiOn/lib/python3.6/site-packages/_magnum.cpython-36m-x86_64-linux-gnu.so: file too short

Also, getting the same error message on testing the installation for habitat-lab. Below is the complete dump.
