I made my first steps in deep learning by following this tutorial https://www.youtube.com/watch?v=wQ8BIBpya2k ,and everything was going well until I needed to train the network in jupyter notebook.I tried almost everything and I always get this error "The kernel appears to have died. It will restart automatically." When I check terminal I can see this

OMP: Error #15: Initializing libiomp5.dylib, but found libiomp5.dylib already initialized.
OMP: Hint: This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results.

WARNING:root:kernel 0d2f57af-46f5-419c-8c8e-9676c14dd9e3 restarted
The code that I'm trying to run is fairly simple (even for me who is just starting to get into deep-learning)
import tensorflow as tf
mnist = tf.keras.datasets.mnist
(x_train, y_train),(x_test, y_test) = mnist.load_data()
x_train = tf.keras.utils.normalize(x_train, axis=1)
x_test = tf.keras.utils.normalize(x_test, axis=1)
model = tf.keras.models.Sequential()
model.add(tf.keras.layers.Flatten())
model.add(tf.keras.layers.Dense(128, activation=tf.nn.relu))
model.add(tf.keras.layers.Dense(128, activation=tf.nn.relu))
model.add(tf.keras.layers.Dense(10, activation=tf.nn.softmax))
model.compile(optimizer='adam',
loss='sparse_categorical_crossentropy',
metrics=['accuracy'])
model.fit(x_train, y_train, epochs=3)
val_loss, val_acc = model.evaluate(x_test, y_test)
print(val_loss)
print(val_acc)
I tried out every idea that I had,and went trough almost all same problems on google,right now this is my last hope so thanks in advance
Which version of tensorflow did you download?
It looks like from the error log that there's some OpenMP library issues, I would try reinstalling Tensorflow to the latest stable version.
I had to update my tensorflow (1.13.1) install to get that code working, here's what I output.
WARNING:tensorflow:From /usr/local/lib/python3.6/dist-packages/tensorflow/python/ops/resource_variable_ops.py:435: colocate_with (from tensorflow.python.framework.ops) is deprecated and will be removed in a future version.

Depending on what library manager you are using, try upgrading
For Pip & Python3:
pip3 install tensorflow --upgrade
For Anaconda:
conda update tensorflow
Then run
import tensorflow as tf
print(tf.__version__)
To verify you have the latest available
