1. When I was building conda package of singa-gpu, I endountered the following error  One available solution is to call `roundf` in CUDA MATH API instead of `std::round ` https://docs.nvidia.com/cuda/cuda-math-api/group__CUDA__MATH__SINGLE.html#group__CUDA__MATH__SINGLE_1ga1c1521079e51b4f54771b16a7f8aeea With this modification, the round test case can pass: ``` root@e7f452d7c67a:~/dcsysh/singa/test/python# python3 test_api.py ................................. ---------------------------------------------------------------------- Ran 33 tests in 1.409s OK ``` By the way, in the docker version of singa, it does not need this change, maybe it is the difference of GCC version in the two environments. 2. This PR updates the numpy to 1.18.5 3. Seems the `cudaDeviceReset()` in destructor returns "driver shutting down" code, we don't need the `CUDA_CHECK`. ``` root@e7f452d7c67a:~/dcsysh/singa/test/python# python3 test_api.py ................................. ---------------------------------------------------------------------- Ran 33 tests in 1.383s OK WARNING: Logging before InitGoogleLogging() is written to STDERR F0630 12:40:39.892601 3077 cuda_gpu.cc:49] Check failed: error == cudaSuccess (29 vs. 0) driver shutting down *** Check failure stack trace: *** Aborted (core dumped) ``` After changed, it works well ``` root@e7f452d7c67a:~/dcsysh/singa/test/python# python3 test_api.py ................................. ---------------------------------------------------------------------- Ran 33 tests in 1.564s OK ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
