ERROR: 'nodes' found as a sub-key in the architecture.

I tried running the command mentioned in the tutorial video of ISPASS2020, but getting ERROR: 'nodes' found as a sub-key in the architecture.

/timeloop/00-model-conv1d-1level$ /src/timeloop/build/timeloop-model arch/1level.arch.yaml prob/conv1d.prob.yaml map/conv1d-1level.map.yaml

input file: arch/1level.arch.yaml
input file: prob/conv1d.prob.yaml
input file: map/conv1d-1level.map.yaml
ERROR: 'nodes' found as a sub-key in the architecture. The 'nodes' key is used by the v0.4 timeloop front-end format, and will not be recognized by 'timeloop-...' commands. Please use the timeloopfe front-end, which is documented at https://github.com/Accelergy-Project/timeloop-accelergy-exercises and https://timeloop.csail.mit.edu/.

Sorry about that. The video is now a little outdated, and our interfaces have changed since we published it.

The error message is correct. You have 2 options:

• Use the 778460fb63ce6c3724b6fd6b5a0482bc5d8c2a25 commit for timeloop-accelergy-exercises (ideally with Release v3.0.3 of Timeloop)
• Use the latest head of both timeloop-accelergy-exercises and timeloop, but use them using the new timeloopfe frontend: https://timeloop.csail.mit.edu/v4/python-interface

Do I understand correctly, that the command-line tools are therefore unable to parse the current architecture yaml format?
