我尝试在/ examples / pycaffe中运行linreg示例。
我为它添加了一个solver.prototxt。
然后我尝试训练它，但是我得到了一个错误。
你能帮助我吗？
我添加的solver.prototxt：
net: "${caffe_dir}/examples/pycaffe/linreg.prototxt"
display: 40
base_lr: 0.1
lr_policy: "step"
stepsize: 320000
gamma: 0.96
max_iter: 600000
momentum: 0.9
weight_decay: 0.0001
snapshot: 40000
snapshot_prefix: "test"
solver_mode: CPU
错误信息为：

解决了！
那是因为python-protobuf的版本是3.2.0，但sudo apt-get install libprotobuf-dev安装的protobuf是2.5.0版本。
所以，让两个版本相同可以解决这个问题。
