Module not found error after updating

[Pablodefelipe]

Dear developer team,

After updating to version 1.3 using git commands, I re compiled the UVLM and xbeam libraries as well as setting the sharpy environment and sourcing the sharpy variables. For reference here is some background on where and why I am using SHARPy:
OS: Ubunut 20.04 running via virtual box
Use: Final Year Project at Imperial College London
The error log I am getting from the unit test is copy pasted at the end.
I also tried to run one of the jupyter notebook examples:'linear_goland_flutter' and I manage to get to step 17 where the sharpy program is called. I attach the error as a screenshot.

I am not sure if this is enough information to be able to give a possible solution, I was thinking of deleting and re-installing, as I had sharpy working before I updated it.

Many thanks!

Hi Pablo,

You'll need to update the conda environment to include those modules that are now used in 1.3

conda env update -f <path_to_environment_file> should hopefully fix it.

I added an explicit note to the release notes.

Thanks,
Norberto

Hi，Ngoiz，
I tried to update my conda environment, but it told me "file not found" as shown in the picture. Can you help me?

[ngoiz]

Hi, you are not updating the environment correctly. <path_to_environment_file> as shown in the answer refers to the environment file that comes with sharp, i.e. utils/environment_linux.yaml (or as appropriate)

Thanks,
Norberto

Hi, Ngoiz, I am using the 2.0 version right now but I have the same error also after updating the environment as you suggested.

Thank you in advance.

Dear alee269,

Your problem is discussed in this issue #227. The solution to your particular problem is to update Python to version 3.10 on your machine.

Thanks,
Steffi

[alee269]

Thank you, it worked. Anyway I have a new type of error after the same command. Could you please help me?

Thank you.

Try using environment_new.yml as it contains the latest python 3.10 requirement.

Should I change anything in the file before creating the environment? Thank you.

Thank you, it worked. Anyway I have a new type of error after the same command.

I opened it from this path: /sharpy/docs/source/content/example_notebooks
Can you please help me? Thank you in advance.
