At first, my environment is ubuntu 18.04, torch 1.2(which is recommended in SReC), python 3.7, nvcc 10.1, gcc 5.4.0, which is the same as environment shown in this repo.
And I met errors below:
Compiling, cuda_support=False

And then my partner realize that in L3C there's a line. They say that torch We tested this code with Python 3.7 and PyTorch 1.1. PyTorch 1.2 is not supported, but progress is tracked in #5.
then i retry with torch 1.1. Everything is OK then.
