【问题描述】:
我正在尝试使用 TBB 而不是 OpenMP 从源代码构建 PyTorch,但我每次都收到以下错误:
/usr/bin/ld: <PATH>/pytorch/build/lib/libtorch_cpu.so: undefined reference to `omp_get_max_threads'
/usr/bin/ld: <PATH>/pytorch/build/lib/libtorch_cpu.so: undefined reference to `omp_get_num_threads'
/usr/bin/ld: <PATH>/pytorch/build/lib/libtorch_cpu.so: undefined reference to `GOMP_barrier'
