ModuleNotFoundError: No module named 'ruamel_yaml'

[philippklughardt]

Hello DemandRegioTeam,

I have recently installed disaggregator and would like to use the demand time series for households and CTS/Industry in my thesis.
I have studied the demos and ran some tests on a jupyter notebook. In the General settings and functions, after importing the respective packages and modules from the disaggregator and running the following commands

• ec_pop = spatial.disagg_households_power(by='population', weight_by_income=False)
  ec_pop.head()

• df_spat = spatial.disagg_households_power('population', weight_by_income=True) * 1e3
  df_spat

• config.dict_region_code(raw=True).head()

it always yields this error: "No module named 'ruamel_yaml'".
See the error message below.

Your help with this issue would be very much appreciated.

Hello Philipp,
i also had this error. I changed every 'ruamel_yaml' to 'ruamel.yaml' and now it works. Hopefully this works for you as well. Maybe you can help me as well, because i'm struggeling to get the load profiles for industrie sectors WZ 10-33 which they used in this model. I only found the 5 sectors on the Website where they used regression analysis but i need all sector for my thesis.
Greetings
Alexander

Hello Alexander,
unfortunately this does not work for me. Maybe the YAML Spec causes problems, but I do not know how to change it within the disaggregator package. You can download the 32 load profiles as a zip package here: https://zenodo.org/record/4576494#.YdwWfRPMLtM
Is this what you are looking for?

Hi Alexandar and Philipp,

I am experiencing the same issue. I cloned the repository from git and set up the environment as described in the read me. Almost every command I run in the notebook reuslts in the error: No module named 'ruamel_yaml.

Alexander, how / where did you change the module name to ruamel.yaml?
Philiipp, did you find another solution?

Thanks
Johann

Thank you for your interest and raising this. I will soon add the ruamel.yaml package to the requirements list, then it should install as a necessary package. Until then you can install it manually via pip install ruamel.yaml as described here.

[philippklughardt]

Thank you for your answer. It worked for me, however it is necessary to activate disaggregator by conda activate disaggregator before installing pip install ruamel.yaml. Otherwise the package will be installed in the local anaconda directory, where it is usually included in the latest python package.

Hey guys, I installed the current ruamel.yaml with pip install ruamel.yaml. And changed ruamel_yaml to ruamel.yaml in teh config function. Now it appears to be working.

A more simple solution is installing ruamel_yaml
