It is unexpected to see this kind of error in step4. Because we often run both two cases(step3 and step4)
I suggest you to narrow down in step4 by
- changing the mapping, i.e., change
-v /home/ubuntu/DBI-9/Transfer/WindowService:/workspace/tao-experimentsto others.
For example,-v /home/ubuntu/DBI-9/Transfer/WindowService:/home/tao/ - changing to another dataset. For example, use a dataset which is confirmed to work previously.
BTW, please check if there are symbolic links in your datasets.
