Problem building

[payamn]

I followed the instruction from http://heterocl.csl.cornell.edu/doc/installation.html.
During the build process, I got the following error (I am using ubuntu 18):

It seems like the error is caused by some other Python packages. I don't think we are using the kiwisolver package as shown in your error message. I would suggest you use Conda to create a clean environment and use Python 3 instead of Python 2 to install HeteroCL. Please let me know if this solves the problem. Thank you!

Thank you, that solved the problem.
