3 years ago Hello - sorry about this and thanks for bringing it up - we are currently in the process of moving to AWS to host weather data. This will make input data management much easier in the long term - but will cause some short-term pain. We are currently unable to share login details for the private AWS account (Amazon won't let us!) This will be resolved as soon as we can. In the meantime, you'll have to download ERA5 data manually using the ERA5_downloader python file - or shoot me an email and I can send you some weather data for Alberta to get you going. Once the weather data is in your inputs folder, you should no longer get this error.
We're also working to update LDAR-Sim to not require weather data - stay tuned, won't be long.
Hi,
Today I tried to install and run LDAR Sim. I encountered an issue with the credentials. I hope you can assist with this issue.
I followed the instructions in the GitHub page. Once the environment was created, I ran the ldar_sim_main.py using Spyder (from Anaconda navigator). While running the file, I encounter the following error message:
Here is the entire text:
