sh make.sh error

[Tuyota]

I use python3.6(anaconda) and CUDA8.0 and sm_52(TITAN X)
when I run sh make.sh, error occurs:

@Tuyota i think it ，u have used python3.6 . i have same problem zhu shi xiong

@Tuyota i had the same problem. note the error: 'for' loop initial declarations are only allowd in C99 or C11 mode(for (size_t i =0 ; i<=len; i++)). it seems like the 'i' need to be declared first.
So, i solved the problem by modify the THMath.h . like
size_t i =0;
for (i;i<=len;i++)
...
