Some errors when I run ringtest.py
Posted: Tue Apr 11, 2017 3:43 am
I installed the neruon from github, the python version is 2.7.12. When I tried to run ringtest.py, there arised some errors.
When import neuron, it prints:
When I run "python ringtest.py", it prints: AttributeError 'hoc.HocObject' object has no attribute 'nrnbbcore_write' as follow:
So I try to use special to run ringtest.py. First I use nrnivmodl to generate x86_64/special and it successed, then I run ringtest.py by "x86_64/special ringtest.py", but it still print an error undefined symbol: hoc_register_dparam_semantics as follow:
Could you please tell me how to solve these errors? Thank you!
When import neuron, it prints:
