8 years ago Hello,
I haven't seen this error before; it is occurring within CVXOPT as you say (doesn't seem to be a missing dependency). Is it possible you are importing another module named "base" that is conflicting with the CVXOPT "base" module? You can try running the CVXOPT example code to see if that breaks too. Otherwise, you might ask the CVXOPT folks about this: https://github.com/cvxopt/cvxopt

Hey there, I was happy to see this extensive work on Multiple Instance Learning, but I ran into an error running your example code. Could it be that I installed it or its dependencies incorrectly? The problem is in cvxopt. Am I not using the correct version?
