DimensionMismatch("No precise constructor for RBState found. Length of input was 4.") #2

Open wly2014 opened 2 years ago

Sorry, why do I meet an error when I run the code x = zeros(model)[1] in Quadrotor.ipynb:

DimensionMismatch("No precise constructor for RBState found. Length of input was 4.")
Stacktrace:

The problem is with the newest version of Rotations.jl. They broke some compatibility with the previous version. For now just use v1.0 of Rotations.jl and that should fix the issue.

Sorry, after I changed the version of Rotations.jl to v1.0.4 using ]add Rotations@v1.0, I still met this error.
