pytorch gcc version compatibilit

install torch supported package e.g., torch_scatter, torch_sparse, requires higher gcc version. Usually miniconnda/ananconnda defaults with gcc 4.8, the compiler is not compatible with pytorch. Do as follows:

conda install -c conda-forge gcc_linux-64

conda install -c conda-forge/label/gcc7 gcc_linux-64

conda install -c conda-forge/label/cf202003 gcc_linux-64

be cautious with other compatibility issues:

1) cudatoolkit, cudnn, nvcc -v

2) package version downgrade, specify version

pip install torch-scatter==1.3.1
