Issues with Fiona due to conflict with existing conda environments

[Francesca1305]

Hello, I tried multiple times to run CEA and I had issues with fiona and geopandas. I installed fiona, geopandas and gdla multiple times from Terminal, but I am facing this error when uploading the shp in the dashboard.

The above exception was the direct cause of the following exception:

@Francesca1305 thank you for reporting this.

Would you be able to give us more information regarding on how you have installed CEA (e.g. CEA version) and how you are using it.

[Francesca1305]

I initially downloaded CEA from the website, but encountered errors when running the dashboard.
Then, i tried from terminal, even if i needed to install some dependencies, as gdal, geopandas, fiona. The installed version is 3.11.
Running it from the terminal, I was finally able to launch the dashboard, but the previously mentioned error appeared when uploading the .shp file.

[reyery]

What were the errors you encountered when running the dashboard the first time? When you wrote version 3.11, did you mean CEA version 3.11 or python 3.11?

[Francesca1305]

CEA_error.log
Please find attached the errors I've encountered.
I downloaded the version 3.39 from the website, but the cea --version shown from Terminal is 3.11. The python version 3.8.
Hope this helps

[reyery]

Thank you for the error log. Based on the error message, it seems to have something to do with the space in the path that is causing the installation of the environment to fail. We are fixing this and would create a new release in the next few days that should solve this issuse

[Francesca1305]

I run it from CEA console directly and I downloaded the release of the link you mentioned in the previous comments

Could you run which cea and pip list in the CEA Console and paste the outputs here

It does seem like there is a conflicting conda environment in your PC that is interfering with the one that was installed.
I think what you can try to do is to delete any CEA environments you have in the conda and try installing CEA from source.
You can try running these commands to try to remove the CEA environments using the CEA console.

# Look for any cea related environments
conda env list

# Remove any cea enviroments, replacing CEA_ENVS with the environment names as listed by the command above
conda env remove -n CEA_ENVS

Then you can follow this guide in the documentation, and run the commands in the CEA console.

Let me know if that works.

Thank you so much for your help. I was finally able to open the dashboard and input the first commands. However, when running the radiation tool, I have a problem with reading the weather file

b''

So far, I tried to reduce the number of considered buildings, the epw file on which the simulations are based on, but i guess there are still some problems with the installation of daysim

[reyery]

Based on the error log, I think it is caused by Daysim not recognizing the weather file and not due to installation.
Make sure the the epw file that you provide is in the correct format.
