OpenSSL 3.0.8 not compatible with PyKX?

Community Support

Hi all,

 

We’ve installed PyKX with pip on an Amazon Linux EC2 instance, and when importing the package in a python session there are some “libcrypto* missing” errors. It seems like these might be associated with OpenSSL 1.1, whereas we have 3.0.8.

Is a certain version of OpenSSL required to load PyKX, or could this be some other issue?

This message is warning about the underlying kurl.q library only.

PyKX has still imported and will still function (apart from any kurl features)

If you wish to use kurl then the requirements are listed here:
