  • OpenSSL 3.0.8 not compatible with PyKX?

    Posted by eohara_kdb on July 3, 2023 at 12:00 am

    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?

    Linux version:

    [ec2-user@ip-172-31-23-74 ~]$ cat /etc/os-release
    NAME="Amazon Linux"
    VERSION="2023"
    ID="amzn"

    PRETTY_NAME="Amazon Linux 2023"
