Hi all, especially Marcin of course, I just wanted to report how the setup of gretl4py worked for me in practice, nothing special. This is an old computer (Sandybridge 4-core) running Windows 10. So first I did a fresh install of the latest Miniconda variant of the Anaconda Python distribution. This has Python 3.12, I think. Right after installation I updated conda inside Miniconda, and then I proceeded following the instructions on https://gretl.sourceforge.net/gretl4py.html - meaning I installed numpy and tabulate within Miniconda in the standard way. (Using the "Anaconda PowerShell Prompt"; numpy also pulled in the Intel MKL with >150MB, but hey...) Earlier I had also installed gretl 2025a. Then I downloaded gretl4py.zip and extracted it somewhere. In the Anaconda prompt I navigated to where I had extracted it and ran "python.exe install.py" successfully. Finally I did as described on the web page and ran estimators.py inside the demo dir, also successfully. So everything went fine so far - I wasn't entirely sure whether the standard Python distro was needed, but Mini/Anaconda seems to work OK. The only thing is that the demo output was so long that I couldn't scroll back all the way in the console (prompt) window - I only got until Model 2 and couldn't see Model 1. I'm sure the console settings could be adjusted somewhere, but as I said, I wanted to test as a standard user with default settings. thanks sven
