Unable to run entity resolution task

[nyy477]

When I run the DeepER task with the command:
bash Run_DLER.sh Abt-Buy Abt Buy no no no

I received this error "attempt to index local 'file' (a nil value)" when reading dataset.

How can I solve this issue?

Here is the console output.

Other Fine Grained Parameters like data splitting, neg/pos ratio, columns to include, etc. can be controlled inside the script

No Sampling was done!
