Hey,bro! I met the same problem,have you solve it?

[ijsmallman]

Just delete it or change len so that it checks the length of the relevant vector.

I had so many issues getting caffe to run with python 3 that I gave up in the end and just went with darknet/tensorflow.

[ijsmallman]

There are lots of issues that python 2 let slip through the net but python 3 wont. Good luck

@ijsmallman thank you very much! I had delete len>0;but there is another problem TypeError: 0.0 has type <class 'float'>, but expected one of: (<class 'int'>,)

[ijsmallman]

I had exactly that problem. You can cast it to an int but then you will have problems later. Like I said, I gave up with Caffe, it is just a mess.
