Error when saving wrapper #132
Description
I have created a wrapper that inherits from BaseModelWrapper. After building the model I try to save it into a pickle with this command:
GTSM_wrapper.save_model(model_path="Snellius_GTSM_model.pkl")
And I get this error:
(bluemath-dev) [vfernandez@int4 GTSM_bluemath]$ /home/vfernandez/.conda/envs/bluemath-dev/bin/python /home/vfernandez/repos/GTSM_bluemath/GTSM_create_simulations.py
Traceback (most recent call last):
File "/home/vfernandez/repos/GTSM_bluemath/GTSM_create_simulations.py", line 26, in <module>
GTSM_wrapper.save_model(model_path="Snellius_GTSM_model.pkl")
File "/gpfs/home1/vfernandez/repos/bluemath_tk/bluemath_tk/core/models.py", line 239, in save_model
pickle.dump(self, f)
TypeError: cannot pickle 'weakref.ReferenceType' object
I have debugged the error and the error is triggered because the self._logger and self._env variables are not serializable. If I exclude them, the save method works.
The error can be reproduced running the script GTSM_create_simulations.py of the GitHub repo https://github.com/fernanqv/GTSM_bluemath
