What version of protoc is required ?

[lovekesh-thakur]

While running the command
./caffe-enet/build/tools/caffe train -solver ./prototxts/enet_solver_encoder.prototxt

I am getting the following error.

Traceback (most recent call last):

TypeError: init() got an unexpected keyword argument 'file'

I have compiled protobuf from source.
Here's my result from command 'which protoc'
/usr/local/bin/protoc

My current version is 3.5.0.
Please help guys. I have already spent half day working on this.

[EDIT]
I rebuild the protobuf with version 3.3 and it worked.
Thanks
