i’m not sure if it’s relevant to gcc version. Please help me.

Mh, GCC version seems fine to me. My guess is that your anaconda might be messed up. Do you work with different Python versions? I would recommend starting from a clean one.

i just reinstalled the anaconda and upgrade the python version to 3.6, the problem is solved! Thank you very much for your adivce and patience!!!

In addition, it would be helpful if you could report the installation log of torch-scatter.
