I am using TensorFlow's Variable for my classification problem. The number of output classes are 1e8.
n_inputs = 5000
n_classes = 1e8
features = tf.placeholder(tf.float32, [None, n_inputs])
labels = tf.placeholder(tf.float32, [None, n_classes])
h_layer = 256
weights = {
'hidden_weights' : tf.Variable(tf.random_normal([n_inputs, h_layer])),
'out_weights' : tf.Variable(tf.random_normal([h_layer, int(n_classes)]))
}
bias = {
'hidden_bias' : tf.Variable(tf.random_normal([h_layer])),
'out_bias' : tf.Variable(tf.random_normal([int(n_classes)]))
}
While running this code, I am getting ResourceExhaustedError for allocating 'out_weights' with (256,100000000). Is there anyway I can overcome this issue?
FYI : I am running this code in CPU.
