Tyofo commented 1 year ago

i can't load my work for my project this very annoying, and i not understand clearly the error

when i have finish to execute : ga_instance.run() i save the work with : ga_instance.save("midas")

i get a warnings: WARNING:tensorflow:Compiled the loaded model, but the compiled metrics have yet to be built. model.compile_metrics will be empty until you train or evaluate the model. INFO:tensorflow:Assets written to: ram://5541c4a9-5e22-4f3e-a6cc-dca25eaf7fed/assets WARNING:tensorflow:Compiled the loaded model, but the compiled metrics have yet to be built. model.compile_metrics will be empty until you train or evaluate the model.

i execute: loaded_ga_instance = pygad.load(filename="midas") i got this error: FileNotFoundError: Unsuccessful TensorSliceReader constructor: Failed to find any matching files for ram://e787696c-9043-4614-8a19-b5a25761d5fc/variables/variables You may be trying to load on a different device from the computational device. Consider setting the experimental_io_device option in tf.saved_model.LoadOptions to the io_device such as '/job:localhost'.

During handling of the above exception, another exception occurred:

FileNotFoundError: Error reading the file midas. Please check your inputs.

how i resolve this error please ??

Can you share a working code to try? I doubt the issue is due to SavedModel, not pickling the PyGAD instance.
