Re: Data exchange from excel to gams (on macOS)
Hi, Your Connect code fails since the symbols Elastva , Elastx , and Elastmu want to read from the worksheets sheet , acelastx , and friscelast which do not exist in the attached Excel file.

Re: Python API: Catching Warnings
Jan,
We did change the implementation of those warnings in the Python Control API to use the warnings module instead of print(). This will become available with the next major release of GAMS.

Re: embeddedcode: Python
Hi, With gams.get() in embedded code Python, you will get all values of a symbol - e.g. level, marginal, etc. for a GAMS variable and need to process them manually afterwards. Here is some code snippet that reads and prints a variable x : embeddedCode Python: var_x = list(gams.get('x')) print(var_x)...

Re: Data exchange from excel to gams (on macOS)
Hi, The error indicates that you try to set data for your parameter twice. Perhaps your parameter has data already and you try to set data again from an embedded code section. Anyhow, the following code should bring the data from the Excel sheet into a two dimensional GAMS parameter: Parameter p(*,*...

Re: Python API picking up wrong GAMS version
Hi,
Something seems to put in the GAMS 38 path into your configuration. Have you checked if the PYTHONPATH environment variable is set? Run from the Anaconda command prompt:

Re: GAMS Installation Error
Hi, This is a Windows problem that can most likely be prevented by running the installer from a command prompt with /SILENT or /VERYSILENT. There is a note on this in the documentation: https://www.gams.com/latest/docs/UG_WIN_INSTALL.html image.png 1. Open command prompt 2. Switch to directory conta...

Re: ModuleNotFoundError: No module named '_gams2numpy'
Jan,
With setuptools>=60.0.0 a breaking change has been introduced. Due to this breaking change the GAMS Python files are not installed correctly. To solve the issue, please try setting SETUPTOOLS_USE_DISTUTILS=stdlib before running setup.py
Let me know if this helps,
Clemens
