your reports says at the end:

ImportError: 
/home/katsu95i/anaconda3/lib/python3.6/site-packages/sage/matrix/../../../../libgd.so.3:
 
undefined symbol: libiconv 


do you have libiconv installed?
If not, it's a missing dependence in the conda build, so you can install 
it, and then sage should work...
