Unable to create Group (no write intent on file)

I got this error everytime I load my model back from an HDF5 file. Below is my error trace.

Traceback (most recent call last):
  File "D:\Anaconda3New\Datasets\train.py", line 63, in <module>
    model = load_model(args["model"])
  File "D:\Anaconda3New\lib\site-packages\keras\engine\saving.py", line 419, in
load_model
    model = _deserialize_model(f, custom_objects, compile)

    layer_weights = model_weights_group[name]

up.py", line 68, in create_group

ValueError: Unable to create group (no write intent on file)

I have read the below question but seems this is a different problem from what I have been through right now.

I can't read data back in using h5py. "unable to create group"

Because I am just loading my architecture and weights from my saved HDF5 file (created after pressing ctrl+c in cmd), how can I assign a mode to this HDF5 file?

Can anybody help me to resolve this issue?

Give write permissions to h5py package before saving your file.

This should work : h5py.get_config().default_file_mode = "w"

See there are two ways of saving a model. A:-

model.save("Model_name.model") and B:-

model_json = model.to_json()
with open(file_name + ".json", "w") as json_file:
        json_file.write(model_json)
model.save_weights(file_name + '.h5')

I believe you were saving the model using the first method and it does not work because of many internal clashes. I recommend that you save the model using second way and then try to reload the model. It will work.

Another possible error might be that since you are saying the model is saved after pressing ctrl + c which is usually used to terminate program and hence it may result in improper saving of file. Try some different key combo.
