there are three places use scatterAdd:

and I read the torch7's code, torch7/lib/TH/generic/THTensorMath.c:

void THTensor_(scatterAdd)(THTensor *tensor, int dim, THLongTensor *index, THTensor *src)
{
long elems_per_row, i, idx;

THArgCheck(dim < THTensor_(nDimension)(tensor), 2, "Index dimension is out of bounds");
THArgCheck(THLongTensor_nDimension(index) == THTensor_(nDimension)(tensor), 3,
"Index tensor must have same dimensions as output tensor");
THArgCheck(THTensor_(nDimension)(src) == THTensor_(nDimension)(tensor), 4,
"Input tensor must have same dimensions as output tensor");

elems_per_row = THLongTensor_size(index, dim);

TH_TENSOR_DIM_APPLY3(real, tensor, real, src, long, index, dim,
for (i = 0; i < elems_per_row; ++i)
{
idx = (index_data + iindex_stride);
if (idx < TH_INDEX_BASE || idx >= tensor_size + TH_INDEX_BASE)
{
THFree(TH_TENSOR_DIM_APPLY_counter);
THError("Invalid index in scatterAdd");
}
tensor_data[(idx - TH_INDEX_BASE) * tensor_stride] += (src_data + isrc_stride);
})
}

but I don't know how to fix this.
I am using Ubuntu 16.04, and tried both LUA52 and LUA53.

PS: the insert code of issue is toooooo bad :(
