Current behavior?
I would expect model.fit to handle training on extremely large NumPy arrays without limitations.
Standalone code to reproduce the issue
import numpy as np
from keras import Sequential
from keras.layers import Dense
n = 2_147_483_648
x = np.zeros(n).astype(np.float32)
y = x
model = Sequential([
Dense(64, activation="relu", input_shape=(1,)),
Dense(1, activation="sigmoid")
])
model.compile(optimizer="adam", loss="binary_crossentropy")
model.fit(x=x,y=y, epochs=1, batch_size=1024, verbose=1)
Relevant log output
ValueError: Invalid value in tensor used for shape: -2147483648
