Dear Nikosl:

I found such issue: "AttributeError: 'module' object has no attribute 'gate'" when I try to compile the source code. Do you have any idea about this error? Do I miss something?

Best

Lei

Hello, I tried installing the software on another computer. I got the same error when I run the software without running "sudo ldconfig" first. You need to run sudo ldconfig once, after installing the software. This fixed the problem for me.

Thank you very much! It works now. Appreciate your efforts and sharing.

Note this error will also be caused if you ran 'cmake' before you installed swig.

I'm getting a similar problem now where I get the output:

Ran ldconfig and made sure to install swig and reinstall files, but still no luck in changing this.

Turns out by default line 76 is commented out on reader.py on master which is what led to this error. Not an issue with compiling this time!

Issue solved.
