Open timuster opened 5 years ago
python run_experiment.py --dump_data
and the 3 'toy-problems' before trying to run the 4 NN scripts mentioned above.I figured that this can be resolved by properly setting the input layer size in the specific files... I'll let this issue stay 'open' in case you'd like help updating the README (post a comment and I can create a pull-request).
Thanks for the project, Chad!
If I'm following correctly you're saying the INPUT_LAYER
and OUTPUT_LAYER
settings have to be changed for the data sets and that's not clear in the readme? If so feel free to open a PR. An alternative might be to update base.py
in order specify these settings in one place, similar to how DS_NAME
is set there. In fact all those layer settings should probably be in base.py
...
agree, ran into this exact issue. thanks for filling the issue @timuster. happy to help move up those settings once i finish catching up on this dang assignment...
@timuster and @sw-yx I've updated the readme, let me know if you have more to add.
