pysftp.CnOpts() reports "ImportError: DLL load failed: The specified procedure could not be found"

i am using Python 3.7.0 library pysftp version 0.2.9

i don't know why whenever i run the below command i will have DLL load failed error. It is very annoying as i can't find a easy way to sftp to my remote server using python

**>>> import pysftp

cnopts = pysftp.CnOpts()**

ImportError: DLL load failed: The specified procedure could not be found.

Same problem happened to me, seems like an issue with cryptography library, reinstalling it fixed it for me. You can re-install it using pip:

pip install cryptography --force-reinstall
