ModuleNotFoundError: No module named 'nacl._sodium'

Hi guys I'm using windows / python 3.8 / netmiko to automate some network tests. On implementation, I'm seeing the error: ModuleNotFoundError: No module named 'nacl._sodium' When viewing the error, it leads to crypto_aead.py which is calling : from nacl._sodium import ffi, lib Is there another location I can call this from as the module can't be found currently? Thanks in advance. Matt [image: image.png]

Need to upgrade from cryptography-2.1.4-cp35-cp35m-manylinux1_x86_64.whl

Hi Crypto Team, Sending a second email from my work account to make sure you have a good email to respond to. We are currently using cryptography-2.1.4-cp35-cp35m-manylinux1_x86_64.whl but need to upgrade to openssl 1.1.1. I am not sure what the naming convention is, so am not sure what the corresponding filename is on https://pypi.org/project/cryptography/#files. Can you give me any pointers? Thanks very much.

Hi Crypto Team, We are currently using cryptography-2.1.4-cp35-cp35m-manylinux1_x86_64.whl and I need to upgrade to openssl version 1.1.1. I am not familiar with what cp35-cp35m and manylinux1 mean in the file name, so I am not sure what the matching version is on https://pypi.org/project/cryptography/#files Can you give me any pointers on this? Thanks for your help and great work. Scott Forman scforman(a)cisco.com
