If we use pre-trained network for transfer learning then does sess.run(tf.global_variables_initializer())
also initialize pretrained weight or not?
if i don't use this then I gets error like this-
FailedPreconditionError:Attempting to use uninitialized value train/beta2_power_1
i am using new Adam optimiser named as "new_Adam"
train_step = tf.train.AdamOptimizer(1e-4, name="new_Adam").minimize(cross_entropy)
my old model already has an Adam node and not letting me to redefine with same name.
Actually my concern is that i want to do transfer learning where I am not sure whether sess.run(tf.global_variables_initializer())
change my trained weights. How can i go for proper transfer learning?
You can initialize your pre-trained model by import your weights model. for example
base_model = keras.applications.MobileNetV2(input_shape=in_img ,include_top=False, weights='mobilenetv2.h5')
then apply your own network
out_class=10
x=base_model.output
x=GlobalAveragePooling2D()(x)
x=Dense(1024,activation='relu')(x)
x=Dense(1024,activation='relu')(x)
x=Dense(512,activation='relu')(x)
preds=Dense(out_class,activation='softmax')(x)
model=Model(inputs=base_model.input,outputs=preds)
out_class is number of classification
