I’m trying to run the workflow from the above title blog. I get the follwoing error message from the Python propogation node. I’ve done propogations before with no problems. Help would be very appreciated.

ERROR Conda Environment Propagation 3:212:0:197 Execute failed: OpenSSL appears to be unavailable on this machine. OpenSSL is required to
download and install packages.

Exception: HTTPSConnectionPool(host=‘conda.anaconda.org’, port=443): Max retries exceeded with url: /t//conda-forge/win-64/repodata.json (Caused by SSLError(“Can’t connect to HTTPS URL because the SSL module is not available.”))

I “fixed” the problem by creating a Anaconda environment including openssl and then running the propogation node in the workflow to add the additional required Python modules. Obviously, that doesn’t address why the propogation node didn’t work on its own.

Hi @rfeigel,

that could be also be an issue of your conda version, see another suggestion in this forum post:

In Anaconda I can create environments that include openssl and use them in Knime. I don’t follow how your reply relates to my problems with the Knime Conda Progagation Node.
