decord GPU 编译

GitHub - dmlc/decord: An efficient video loader for deep learning with smart shuffling that's super easy to digest

module load cmake gcc/11.2 cuda/11.8
cmake .. -DUSE_CUDA=ON -DCMAKE_CUDA_COMPILER=/usr/local/apps/cuda/11.8/bin/nvcc -DCMAKE_BUILD_TYPE=Release

第一个问题是gcc版本，如果过低有package依赖问题

第二个问题是ffmpeg version, 4没有通过，5可以把video的folder替换掉

 第三个问题是

OSError: /lib64/libldap.so.2: undefined symbol: EVP_md2, version OPENSSL_3.0.0

export LD_LIBRARY_PATH=$CONDA_PREFIX/lib:$LD_LIBRARY_PATH
export C_INCLUDE_PATH=$CONDA_PREFIX/include:$C_INCLUDE_PATH
export LIBRARY_PATH=$CONDA_PREFIX/lib:$LIBRARY_PATH

可以暂时把conda env的path提前
