Error while executing demo.py

[chanchalIITP]

Hi. I have already downloaded all the required files. Execution of demo.py gives model based error(checkpoint issue). I am attaching the error trace. Please help. thank you in advance.

File "demo.py", line 47, in
model.restore(session)
File "/Data/chanchal_1821cs11/e2e-coref-master_fresh/coref_model.py", line 94, in restore

err, "a mismatch between the current graph and the graph")
tensorflow.python.framework.errors_impl.InvalidArgumentError: Restoring from checkpoint failed. This is most likely due to a mismatch between the current graph and the graph from the checkpoint. Please ensure that you have not altered the graph expected based on the checkpoint. Original error:

I am experiencing the same issue while trying to run the demo in Google Colab, @chanchalIITP - were you able to resolve this by any chance ?

same question

[shon-otmazgin]

this is related to
FileNotFoundError: [Errno 2] No such file or directory: 'char_vocab.english.txt'

?

Here's an idea for anyone else who is having this error and stumbles across this issue: this may be due to not modifying the path in

e2e-coref/setup_training.sh
