为运行Densepose安装Caffe2时遇到了两个问题：

1.python -c 'from caffe2.python import core' 2>/dev/null && echo "Success" || echo "Failure"

Failure

2. python -c 'from caffe2.python import workspace; print(workspace.NumCudaD evices())'

TypeError: __init__() got an unexpected keyword argument 'serialized_options'

错误解决方法:

参考： https://blog.csdn.net/qq_41185868/article/details/82890135

安装正确版本的protobuf(其实就是3.6.1，我也不知道为什么默认使用conda install protobuf安装到的是错误版本)

(pyDense3.6) Xdn@xwfx:~/.conda/envs/pyDense3.6/lib/python3.6/site-packages/torch/include$ conda install protobuf=3.6.1

完整输出如下：

A 错误输出：
