metAMOS INSTALL.py error

[fangyuanchang]

I tried running "python2 INSTALL.py core" and fails with the following last few lines. One difference compared to instruction on the manual was that I had to run with python2 instead of python (which runs on ver 3 as default). Any help appreciated. Thanks!

The above error indicates cython 3 is the default:

/mnt/efs/fangyuan/metamos/metAMOS-1.5rc3/Utilities/python/lib/python/Cython-3.0a6-py3.6-linux-x86_64.egg/Cython/Compiler/Main.py:344: FutureWarning: Cython directive

metAMOS requires python v2 and cython v2 as well. It looks like you didn't completely switch to python2 on the system.

Hi Sergey, I installed python 2.7.14 in a conda environment, installed psutil 0.6.1 (had issues with psutil) and I got the same error message described above. The cython version coming with python 2.7.14 in the conda environment is: 0.29.21. I installed cython 0.25.2 and still got the same error message. Which version of cython do you recommend? Which version of python and cython do you use (I could not find the version 2.7.3 of python)? Any other advice for a complete switch to python2?
