cannot run with --gui

[garrisonz]

Hi, I can run nerf2mesh withou --gui correctly, but fail with --gui option.

This is the error when run with --gui

$ python main.py data/nerf_synthetic/lego/ --workspace trial_syn_lego/ -O --bound 1 --scale 0.8 --dt_gamma 0 --stage 0 --lambda_tv 1e-8 --iters 600 --gui

the error changes after set export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libffi.so.7.

can you help to solve this error? thanks.

The reason of first error undefined symbol: ffi_type_sint32, version LIBFFI_BASE_7.0 is that: libffi.so.7 links to libffi.so.8 link libffi.so.7 in ~/miniconda3/envs/nerf2mesh2/lib to system libffi.so.7.1.0 will solve this problem.

ln -s /usr/lib/x86_64-linux-gnu/libffi.so.7.1.0 libffi.so.7
ln -s /usr/lib/x86_64-linux-gnu/libffi.so.7.1.0 libffi.7.so

but not initialized error still appears
