AttributeError: 'module' object has no attribute 'noValue'

I'm getting this error with both 4.3.5 and 4.3.8. Python version is 2.7.13

Below is a stack trace from a simple app that I wrote which uses pysnmp to read SNMP data (Sorry for the layout -- I tried to insert them as code but that doesn't seem to work):

What is your pyasn1 version? Make sure it's the latest released one.

[ww9rivers]

$ pip search pyasn1
pyasn1-modules (0.0.9)  - A collection of ASN.1-based protocols modules.
pyasn1 (0.2.3)          - ASN.1 types and codecs
  INSTALLED: 0.2.3 (latest)
rfc3161 (1.0.7)         - Python implementation of the RFC3161 specification, using pyasn1

Sorry, my bad! I forgot to check the OS installation of the package.

I removed the OS python-pyasn1 package and reinstalled everything. It works now.

Thank you for your quick response.

Note to self: we should probably rely on the older pyasn1 API to avoid this...
