Разрешение nvcc отклонено при сборке xgboost с поддержкой GPU, ubuntu 18.04

Я создаю XGBoost с поддержкой графического процессора в Ubuntu 18.04, следуя руководству по установке . На этапе cmake .. -DUSE_CUDA = ON происходит сбой с make [1]: execvp: / usr / local / cuda / bin: Permission denied .

Полный вывод приведен ниже.

-- CMake version 3.17.1
-- xgboost VERSION: 1.2.0
-- Configured CUDA host compiler: /usr/bin/c++
-- The CUDA compiler identification is unknown
-- Check for working CUDA compiler: /usr/local/cuda/bin
-- Check for working CUDA compiler: /usr/local/cuda/bin - broken
CMake Error at /usr/local/share/cmake-3.17/Modules/CMakeTestCUDACompiler.cmake:46 (message):
  The CUDA compiler

    "/usr/local/cuda/bin"

  is not able to compile a simple test program.

  It fails with the following output:
