Getting libraries in place.
WHERE THEY MUST GO
Into the virtual environment cPanel created for the application.
Not globally.
HOW TO DO IT
Activate the environment using the command the interface provides, then install.
Or use the interface's own facility for installing from a requirements file.
WHAT TO PROVIDE
A requirements file listing your dependencies with pinned versions.
WHY PINNED
So the installed environment matches what you tested.
WHAT TO DO AFTER INSTALLING
Restart the application.
Changes are not picked up until you do.
THAT POINT
The most common reason a change appears not to take effect.
WHAT CAN FAIL
Libraries requiring compilation Libraries requiring system packages Libraries needing more memory than available during installation
WHAT TO DO ABOUT EACH
Try a pure Python alternative Check whether a prebuilt version exists Open a ticket, describing what failed
WHAT TO KEEP
The requirements file in version control, so the environment is reproducible.
