Problems with Python Layer: Protobuf Internal Error - Mutex Lock

[paridhisrivastava]

Hi,
I am trying to run a Caffe model which includes a python layer. Initially, when I tried to run the model prototxt file, I got an error asking me to update the version of Protocol Buffer to 3.4.0. So I did that by building from the source code. I have also upgraded the protobuf package in python to version 3.4.0. After doing this and rebuilding caffe, I'm getting the following error on running a prototxt file containing the python layer. [Please note that this error does not generate when I run another model without Python layer.]

Also, I'm using Ubuntu 16.04.

Any help/pointers would be appreciated.
Thanks!

Hi,

What is the status of this issue ? I have the same issue with protobuf and tensorflow.

[kodonnell]

This?

Sorry, I can't tell anything from the stack trace... @amauryfa, do you have any idea?

seeing the same in gazebo:

3.4 is too old, wondering if it still an issue for our new version?
