What is the procedure of using IPOPT solver in Azure databricks?

[omran]

I have installed ipopt solver of version 3.11.1 in azure databricks but while running the code it throwing an error -

WARNING: Could not locate the 'ipopt' executable, which is required for solver ipopt

ApplicationError: No executable found for solver 'ipopt'

could anyone please assist me on this issue by telling resolution steps for above error.

Due to conda licensing changes, it is no longer an option for many people. My DBR is 10.2ML

Hello @omran shaik​  In the past, we have recommended customers to use docker containers with Databricks as some of these solvers required native compilation and did not work great on the runtimes.

With DCS you have full control of what you want to install.
