If your model is large because contains many sectors, households and firms, you may try to scale it down and check if it solves when downsized.

Thank you Karol! I’m able to run it on my Linux machines, which makes me happy enough. If I find a way to run it via Brew in Mac OS, I’ll let you know.

Hi Sergio, Manuel, we were able to identify the source of the problem and remediate it. Please download the newest release of the package (1.2.2) and this should work fine both under Windows and Linux machines.

Dear all,

I've been facing the same problem in two different computers, and the solution that worked for me was to execute R-Studio from anaconda (the python environment which allows you to install and run R). Once you install anaconda, instal R-Studio (takes some time) and then try to install the gEcon software. I hope this works for you, I've tried this procedure in both computers and it worked.

Hi Manuel,

the error you encountered is not caused by any new bugs in version 4.2.1 compared to the previous versions. I faced the same issue when I tried to build a model using sets with Ubuntu 18+ and previous versions of gEcon: 1.1.0 and 1.2.0. This may be caused either due to incompatibility of DLLs after upgrade to Ubuntu 18+, update of compiler or some other code issues (possibly with index sets as without them the package works fine). The package should work properly under Windows. We will try to come up with a solution.

Regards,
Karol Podemski

Dear Amando and Prasanta,

I am having the same issue, using R 4.2.3 and gEcon 1.2.1 on Debian Linux. I have tried on two machines, one with Intel processor and a tiny 2GB memory and other with an ARM processor and 8GB memory (Raspberry Pi). The phenomenon is more or less the same on both:

The model I am running is one of gEcon templates, 3-firm static with government. I tried to run "calibration" as well and have a similar issue.

I believe this is a glitch in gEcon 1.2.1 programming, as I can run on 1.2.0 and R 3.5.x in Windows 10 and an equilibrium is found. The problem I have with said Windows machine is that it's really slow.

I know the nice folks in Poland build and maintain this out of their good heart, and I am thankful for that. If I can help in any way, please let me know. I think gEcon is great.

All the best,

Manuel

Hi Prasanta,

I cannot say for sure whether the problem is a memory issue as I do not know your machine and also am not familiar with the package gEcon.

However, the page https://gecon.r-forge.r-project.org/download.html says that some functions are compiled prior to being invoked and this may cause R to freeze. Check the red message towards the bottom of the page, it may be a good place to start.

As I run the function make_model (see screenshot image attached), R session terminates abruptly. Is it due to memory constraints? I reinstalled R, Rstudio, all packages, still problem persists. How could I resolve it?
