error for running mergeUmi

[Xin Li]

Thank you for providing this extractor.
My python version is 3.5.2. I instlled the package and then tried to run merge.sh and got following error:

Thank you for trying. I have disabled python 3 for this package. The python 2 version compiles and passes all tests.
