Issue building prefix_sum #2

Closed yuhao closed 3 years ago

yuhao commented 3 years ago

gcc/g++ version 6.5.0 nvcc version 10.0 Python 3.6.8 on centos 7.9

trying to build prefix_sum and got the following. Any suggestion is appreciated!

prefix_sum.cu(80): error: a pointer to a bound function may only be used to call the function

prefix_sum.cu(80): error: type name is not allowed

prefix_sum.cu(80): error: expected an expression

Mine works with gcc/g++ 7.5.0, cuda 10.2 (10.1 should also works) and python 3.8.2 on ubuntu 18.04. Will check it out after a report deadline in several hours... scan( grid_off.contiguous().data_ptr<int>(), grid_cnt.contiguous().data_ptr<int>(), num_grids, true ); The code looks fine to me. I use this conversion from at::Tensor to type* throughout the library. Maybe you can check your pytorch version? Mine is 1.6.0 and it is working.

Hmm update pytorch to 1.8 seems to do the trick. Thanks.
