Caffe2：python -m caffe2.python.operator_test.relu_op_test

1. 进行语句测试时候，出现问题，

      设置环境变量CUDA_VISIBLE_DEVICES

参考： cuda设置指定可见方法

    

在/etc/profile文件或者～/.bashrc末尾添加以下行：

       export CUDA_VISIBLE_DEVICES=0,1 ##仅显卡设备0,1GPU可见。可用的GPU可通过nvidia-smi -L命令查看

2. 出现     ImportError: No module named hypothesis
     pip install hypothesis

测试成功
