why specify `ignore_index=0` in the NLLLoss function in BERTTrainer?

1

# trainer/pretrain.py ```python class BERTTrainer: def __init__(self, ...): ... # Using Negative Log Likelihood Loss function for predicting the masked_token self.criterion = nn.NLLLoss(ignore_index=0) ... ``` I cannot understand why `ignore...

I often run the network for 1 second before a real simulation to make the neurons reach a steady state. When I start the real simulation, I want to reset...

Wrong coefficient for 1D-QuinticSpline

1

The normalization coefficient for 1D-QuinticSpline is $1/(60*h)$ rather than $1/(120*h)$. Validation: ```python def quintic_spline(r, cut, dimension=3): h = cut / 3 q = r / h w = np.where(q <...

`tests_sycl` is to be compiled regardless of `SPHINXSYS_USE_SYCL` in the master branch (see `tests/CMakeLists.txt`): ```cmake ADD_SUBDIRECTORY(tests_sycl) ``` which will lead to compilation error if users do not install related dependencies....

Following #965 1. Change the parameter `SimTK::UnitVec3` to `Vecd` during constructing the cylinder in the source code. 2. Change `axis` to `SimTK::UnitVec3(axis[0], axis[1], axis[2])` in the body of `TriangleMeshShapeCylinder::TriangleMeshShapeCylinder`. 3....

Use consistent vector types when constructing a cylinder

1

This is not a bug, but a little suggestion. When constructing a cylinder using `TriangleMeshShapeCylinder`, users should provide two vectors, one axis whose type is `SimTK::UnitVec3` and one translation whose...

add gdb extension in tools/
