Reproduce the import in the reported Ubuntu conda environment, then inspect pyculib/sparse/binding.py and pyculib/utils/libutils.py around the failing cuSparse initialization. Compare the requested cusparseCaxpyi_v2 symbol with the installed libcusparse.so.10.3.1.89; done means importing pyculib without the AttributeError.
