Describe the bug
Following error is thrown post developer setup of Hangar in Windows machine while trying to assign a dummy image to repo array set - "OSError: symbolic link privilege not held"

Unexpected Behavior, Exceptions or Error Thrown

To Reproduce
Steps to reproduce the behavior, minimal example code:

import hangar
repo = hangar.Repository('.')
co = repo.checkout(write=True)
co.arraysets.init_arrayset('images', shape=(10,10,3),dtype=np.uint8)
co.commit('arrayset init')
images = co.arraysets['images']
img = np.random.random((10,10,3)).astype(np.uint8)
images[0] = img

images[0] = img
Traceback (most recent call last):

Thanks for the bug report @narendranss! Sorry you had issues. I will take this into account and see if we can't remove the need for symbolic link privliges in a future release!
