Error in initialising pagerec in pregrec.ipynb

[Sammed56Secure]

While running the block

textmodel = None # use default
segmodel = None # use default
# segmodel = "https://storage.googleapis.com/ocro-models/v1/seg_unet_v4-034-000131238.jit"
pagerec = inf.PageRecognizer(textmodel=textmodel, segmodel=segmodel)

I get the output that downloading http://storage.googleapis.com/ocro-models/v1/seg_unet_v2-default.jit to /Users/<user>/.cache/ocropus4/seg_unet_v2-default.jit

but while loading the model step
loading model /Users/<user>/.cache/ocropus4/seg_unet_v2-default.jit

I get an error saying
RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory

Can't move forward from this. the link https://storage.googleapis.com/ocro-models/v1/seg_unet_v4-034-000131238.jit shows 404 error in wget.

Any help in resolving this?
