KeyError: 'user/angle'

Command : donkey train --tub ./data --model ./models/mypilot.h5

ERROR : 2023-02-26 22:35:30.444913: W tensorflow/core/framework/op_kernel.cc:1755] Unknown: KeyError: 'user/angle'

How to solve:

• change manifest.json and catalog_x.catalog
  all "user/steering" >> "user/angle"

Why occurred ? donkey car web controller saved all steering values as "user/angle" not "user/steering"

This is my error. I just merged a change that renamed 'user/angle' to 'user/steering' as part of a larger change, forgetting that this would obsolete old data. I will work on a fix immediately.

@Ahrovan I've made a change in this branch; https://github.com/autorope/donkeycar/tree/1104-fix-user-angle-in-deep-learning It will now again save steering data with the 'user/angle' label ratehr than 'user/steering' However this does not fix data that was saved with 'user/steering',but you say you have a work-around for data that was erroneously saved using 'user/steering':

• To fix data saved with 'user/steering', change manifest.json and catalog_x.catalog all "user/steering" >> "user/angle"

Please give the branch a test and let me know here is this fixes the data recording issue. Thanks and sorry for the trouble.

You will need to

1. from the root folder of your donkeycar repo: checkout the branch

git checkout 1104-fix-user-angle-in-deep-learning

2. make sure the donkeycar python environment is active, then from your mycar folder (the folder where you are running the car from), recreate the manage.py file by overwriting it;

donkey createcar --overwrite --path=.

we can use --path=. because we are already in the mycar folder.

3. Now you can run the car and save data and verify that it is saving steering as 'user/angle'

See PR #1105 for a fix

That PR merged. I've tested in by collecting data, training and driving on autopilot.
