Cannot compile protocol buffers

[padmalcom]

Hi, thanks for your framework. I followed the installation guide but got problems when compiling the protocol buffers. I followed the instructions exactly as you specified, except that I'm working on CentOS whereas you seem to work in Ubuntu.

(deeplab2) [user1@localhost deeplab2]$ pwd
/home/user1/deeplab2/deeplab2
(deeplab2) [user1@localhost deeplab2]$ cd ..
(deeplab2) [user1@localhost deeplab2]$ ls
cocoapi deeplab2 init.sh models
(deeplab2) [user1@localhost deeplab2]$ protoc deeplab2/*.proto --python_out=.
deeplab2/model.proto:178:3: Expected "required", "optional", or "repeated".
deeplab2/model.proto:178:27: Missing field number.
deeplab2/config.proto: Import "deeplab2/model.proto" was not found or had errors.
deeplab2/config.proto:31:12: "ModelOptions" is not defined.

Is it possible that I use the wrong protoc version?

(deeplab2) [user1@localhost deeplab2]$ protoc --version
libprotoc 2.5.0

Hi,

The protoc version could be the issue. I am running 3.6.1. Please have a look here to find newer versions. If this solves the compilation error, please let us know so we can update the requirements regarding the protobuf compiler.

Best,
Mark

Hi Mark,
thank you, I just compiled protoc from github and could get rid of the error messages.

(deeplab2) [user1@localhost protobuf]$ /usr/local/bin/protoc --version
libprotoc 3.17.3
(deeplab2) [user1@localhost deeplab2]$ /usr/local/bin/protoc deeplab2/*.proto --python_out=.
(deeplab2) [user1@localhost deeplab2]$
