Hi everyone,
I’m currently using an external Python script to execute a Grasshopper script that includes Python 3 components for certain calculations. I followed the instructions from the Rhino.Compute Git repository and successfully connected to a localhost.
I can run Grasshopper scripts without issues—provided they don’t contain any Python 3 components. However, when such components are included, the terminal outputs “Python 3 is loading”, after which the Python script stops executing.
Does anyone know how to resolve this issue?
Thanks in advance for your help!

Hi Anton, thanks for sharing your code - I didn’t know how to use RhinoCompute to run any GH definition.
Have you tested it with a “Hello World” Python 3 component?
If that works, can you just increase the timeout on the requests.post call? If a Python 3 component has to install dependencies using pip, it can indeed take a while - is it possible to cache these, and have the Python3 components reuse a Python environment with them pre-installed using # venv: ?
Hi James, thank you for your response. Yes, I tried running a simple “Hello World” script using a Python 3 component, but unfortunately, it didn’t work-Python 3 isn’t loading. I also attempted to increase the timeout, but that didn’t help either. Perhaps I need to replace the Python components in the GH script with Hops functions defined in Python instead.
You’re welcome. Using Hops is worth a quick try if there’re no answers in the Rhino Compute documentation.
It still reminds me of starting Rhino 8 for the first time, and CPython taking a while to set up, or when you delete the whole CPython env to clear imported packages.
