CROP

[Carlos]

Hi!

I'm trying to implement the following example with the latest caffe master version available #4024 : http://lmb.informatik.uni-freiburg.de/people/ronneber/u-net/

However, when I try to run the *solver.prototxt on my data I always get the following error:

[libprotobuf ERROR google/protobuf/text_format.cc:245] Error parsing text-format caffe.NetParameter: 61:85: Unknown enumeration value of "CROP" for field "type".

Do you have idea of why could this be happening? Does the crop layer have a particular different "type" codename??

Thanks in advance for your comments!

Mhm, either your version of caffe or the provided network definition is outdated. Currently a crop-layer is declared as type: "Crop" (note that type has a string value rather than an enumeration value). If the network and/or solver definition is in the old format, you should be able to upgrade it to the new format by running one of the upgrade_* tools from the caffe/tools subfolder.

I'm trying to implement the U-Net as well on the newest version of Caffe on github. I get the same error.

Do you know how to solve it?

Hello,

I am also implementing a U-Net and I have the same error. Did you solve it ?
