Erreur dans UseMethod("compile")

[OusmaneS17]

Bonjour, j'ai construit un modèle en utilisant keras mais j'ai eu une erreur de compilation comme celle-ci:
model <- keras_model(inputs = input_layer, outputs = list(output_revenu, output_data, output_voix))

summary(model)

hello,

I built a model using keras but got a compilation error like this:
model <- keras_model(inputs = input_layer, outputs = list(output_revenue, output_data, output_voice))

summary (template)

model <- compile( + model, + optimizer = optimizer_adam(), + loss = "mean_squared_error", + metrics = list("mean_squared_error"), + loss_weights = list(output_revenue = 1, output_data = 1, output_voice = 1) + ) Error in UseMethod("compile"): no method for 'compile' applicable for an object of class "c('keras.src.models.functional.Functional', 'keras.models.functional.Functional', ' keras.src.ops.function.Function', 'keras.ops.function.Function', 'keras.src.models.model.Model', 'keras.models.model.Model', 'keras.src.backend. tensorflow.trainer.TensorFlowTrainer', 'keras.backend.tensorflow.trainer.TensorFlowTrainer', 'keras.src.trainers.trainer.Trainer', 'keras.trainers.trainer.Trainer', 'keras.src.layers.layer.

Is this with keras or keras3?

Can you please provide a reprex?

The error message looks very similar to an issue that occurred if both R packages {keras} and {keras3} were loaded in the same R session. That issue is now fixed with the latest CRAN release of both packages. Can you confirm you're using the latest CRAN release?

Hello, I don't believe github supports email replies with attachments. Can you please paste the output from running reprex::reprex() into the issue thread using the github UI: #1436

Closing for now since I can't reproduce the error.
