Hi,I am trying to use iced module to normalized Hi-C data.However , there is something wrong 'ImportError: ……/anaconda2/lib/python2.7/site-packages/iced/normalization.so: undefined symbol: PyUnicodeUCS2_Format
make: *** [ice_norm]'
What does that error mean?How can I fix it?
Thanks!

Hi @werhoog
Sorry for the very slow reply. I'm missed the email notification.

this looks like a compilation issue: iced was not compiled with the same options as python. It's a fairly rare error, and I see you are using anaconda and not a manually compiled python, so I'm not sure why that would happen. I think that by reinstalling iced, the compilation flags should be set coherently across everything.
