use --gs_type gs_mesh with colmap dataset

[yungommi]

I have colmap dataset and ground truth mesh
with this command => python train.py --eval -s ./data/mydata -m output/mydata--gs_type gs_mesh
result was => AttributeError: 'BasicPointCloud' object has no attribute 'triangles'

is it impossible to use Colmap dataset with --gs_type gs_mesh?
