Type error with load function

[Lavanya-Bala]

Hi,

I am trying to run the optimisation from the tutorial and the following error occurs.
As far as I can guess, this is a backend issue? Could you please let me know if there is a way to go about this ?

Traceback (most recent call last):
File "\site-packages\pyleecan\Functions\Load\import_class.py", line 8, in import_class
module = import(mod_name + "." + class_name, fromlist=[class_name])
TypeError: can only concatenate str (not "bytes") to str

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "", line 312, in
res = load("opti_out.h5")
File "\site-packages\pyleecan\Functions\load.py", line 111, in load
return init_data(init_dict, file_path)
File "\site-packages\pyleecan\Functions\load.py", line 51, in init_data
class_obj = import_class("pyleecan.Classes", obj.get("class"), "")
File "\site-packages\pyleecan\Functions\Load\import_class.py", line 20, in import_class
"Unknow class name " + class_name + " when loading"
TypeError: can only concatenate str (not "bytes") to str

Hello,

What a coincidence, I'm working on this tonight (and maybe tomorrow as well) so I have seen this error message too many times: the issue here is the version of h5py. I expect that you are using a version >3 and the current requirements of pyleecan is h5py==2.10.0. Reverting your version of the package to 2.10 should solve your problem.
I currently working on making pyleecan work with the latest version of h5py so hopefully it shouldn't happen again.

Best regards,
Pierre
