Re: Modify multidimensional parameter with Python GamsModelInstance
Please have a look at the transport7.py example: https://www.gams.com/latest/docs/apis/examples_python/transport7_8py_source.html Although it doesn't show how to modify a two dimensional parameter, it shows both the use of a scalar parameter and a two dimensional variable. Instead of adding a scalar...
Re: model2tex
It seems that in your GAMS code you did not define an actual model. This is required
since model2tex is meant to create documentation for a specific model in your GAMS code.

Re: Installing Python API
1. The GAMS Python API is installed using distutils. As far as I know there is no automatic way of uninstalling a package/module that was installed using distutils. If you have accidentally installed the wrong version of GAMS Python API files, you might try to run the setup.py script from the correc...

Re: Installing Python API
I read this over, sorry. Support for Python 3.6 was added recently in GAMS 24.8.4. If you ran the setup script from the directory 'api', you have installed the Python 2.7 version which is not compatible with Python 3.6
Best,

Re: Installing Python API
The GAMS Python API comes in separate directories for different versions of Python. Please have a look at the 'Getting Started' section of the tutorial and make sure that you install the correct files for your version of Python: https://www.gams.com/latest/docs/apis/examples_python/index.html Best, ...

Re: Python API, Jupyter, Solver Log
Jan, The GamsModelInstance is a high performance class meant for solving an instance of a GAMS model multiple times (with different data). Currently it is not possible to direct the (debug) output to Jupyter. We will have a look at the implementation details to see if we can make this work. Best, Cl...

Re: How to make communication of C to Gams?
Maria, you might want to have a look at "apifiles/C" in your GAMS installation directory. The examples "xp_example1.c" shows how to read and write GDX files. The example "xp_example2.c" shows how to call a GAMS model programmatically from within your C program. Best, Cl...

Re: [python API] Running GAMS through Jupyter notebook
Samarth, it should not make too much of a difference whether you are running Python from Jupyter or from a usual cmd prompt. I just installed Anaconda 2.7 (64 bit on Windows) to give the GAMS Python API a try in a Jupyter notebook. After installing the API from the command line using the Python vers...
