Can you provide some more details on how you installed GemPy? Did you install it in a virtual environment or conda environment (and with which Python version)?

Can you provide some more details on how you installed GemPy? Did you install it in a virtual environment or conda environment (and with which Python version)?

i am using with anaconda and saw some video i hv tried in different ways some are following ...

1. i direct put pip install gempy in the cmd ...and the its showed command already satisfied ..but when i am using in jupyter is shows error which i mentioned above

2. second way is i created a conda enviroment then i put conda install theano..... but its not successfully done ..it showing some unsuccessful frozen solve error.....

3. then i reinstall anaconda old version which using python 3.9 but same error

4. i also tried with google colab and its running but on google colab i think its not fully functional ..i tried the same code which you mentioned in the website tutorial but some code is running some is not working ...

i really need help please some one explain me how to use gempy and its coordinates....

Also i want to know what kind of data i can import for 3d visualization ....and how to import data into my code ....plz help

Hello @Varun019140,
first of all, great to see that you are using gempy. You opened multiple issues over a very short period of time and as we are trying to keep this area strcutured I would suggest a couple of things:

• Please make sure to wait for a response until you open new issues, and close your issues if they are resolved
• While printed error messages are often useful, a clear written description of the problem is most important to us. Please also make sure to use a well readible style and we also appreciate a little effort on spell checking etc.

With this in mind, how much experience in this area do you have? Gempy is an open source modeling tool. We aim to make it accessible to people with little coding experience, but you will still need to invest some time and effort. And while we are trying our best to create a smooth experience, we will not be able to help with all problems - especially if they are not based in gempy.

Regarding your issues: I will close all your other issues for now and would like you to ask your questions here. As a starting point: Following the current installation guide, I would suggest installing gempy using pip in a fresh environment with python 3.12. Theano is not required anymore so you were maybe following an old guide (also videos on youtube do not cover the new version that was just released).

Please try this installation and let us now exactly where you encounter problems.

Good luck and cheers

I will close this for now, please feel free to reopen if you still have specific questions.
