ImportError: No module named google.protobuf.internal about open_nsfw HOT 6 OPEN

I've got the same problem when I tried installing caffe. I solved it by reinstall:
sudo pip install protobuf
Reference link: https://groups.google.com/forum/#!topic/caffe-users/9Q10WkpCGxs
The another error: libdc1394 error: Failed to initialize libdc1394. I solved it by:
sudo ln /dev/null /dev/raw1394

from open_nsfw.

And when i run 'sudo docker run caffe:cpu caffe --version', it shows
'
libdc1394 error: Failed to initialize libdc1394
caffe version 1.0.0-rc3
'

Thank you, XuefeiWen. Before i opened this issue, i had tried some ways like you advice, but it didn't work. I guess it occurred because of my computer, i will try again on another machine. Thanks a lot. @XuefeiWen

I hit "libdc1394 error" too, and "sudo ln /dev/null /dev/raw1394" did not work in my two ubantu sytems (both of them were inited from VM) .... Is this a fatal issue? I can see it did not block follwoing process.

I have meet the similar question.when I input the commond:docker run --volume=$(pwd):/workspace caffe:cpu python ./classify_nsfw.py --model_def nsfw_model/deploy.prototxt --pretrained_model nsfw_model/resnet_50_1by2_nsfw.caffemodel test_image.jpg
it failed with the output:
libdc1394 error: Failed to initialize libdc1394
Traceback (most recent call last):

I have tested in another computer with ubuntu system which is not inited from VM, it still has the same problem("libdc1394 error"). So i guess it's none of the VM's business. And i ignore the notice and try running "sudo docker run --volume=$(pwd):/workspace caffe:cpu python classify_nsfw.py --model_def nsfw_model/deploy.prototxt --pretrained_model nsfw_model/resnet_50_1by2_nsfw.caffemodel 1.png", it works! And you could ignore that problem, too. If you hit "ImportError", please test it with ubuntu system which is not inited from VM. @XuefeiW @willswl @ZhaoQiang2015
