Technical problem

benjsce · December 26, 2022, 10:23am

Hello, I installed Tensorflow on my macbook m1 following this method:
https://github.com/jeffheaton/t81_558_deep_learning/blob/master/install/tensorflow-install-conda-mac-metal-jul-2022.ipynb

However, when I create a machine learning algorithm with tensorflow and keras, I get this message:

2022-12-26 11:16:53.762852: I tensorflow/core/common_runtime/pluggable_device/pluggable_device_factory.cc:306] Could not identify NUMA node of platform GPU ID 0, defaulting to 0. Your kernel may not have been built with NUMA support. 2022-12-26 11:16:53.762897: I tensorflow/core/common_runtime/pluggable_device/pluggable_device_factory.cc:272] Created TensorFlow device (/job:localhost/replica:0/task:0/device:GPU:0 with 0 MB memory) → physical PluggableDevice (device: 0, name: METAL, pci bus id: )

Metal device set to: Apple M1

What can I do to fix this?

Thanks

@benjsce,

Welcome to the Tensorflow Forum!

Usually, NUMA is a harmless warning. You can safely ignore the above messages. Here I is an information not a warning.

Is there any issue when running the model?

Thank you!

Thanks for your answer.
Yes, I have an error :

when I run this line :

network.fit(train_images, train_labels, epochs=5, batch_size=128)

Jupyter return to me :

@benjsce,

In order to expedite the trouble-shooting process, please provide a code snippet to reproduce the issue reported here. Thank you!

benjsce · December 27, 2022, 9:49am

Here’s the code :

from keras.datasets import mnist
import numpy as np
import tensorflow as tf
from tensorflow.keras import models
from tensorflow.keras import layers

(train_images, train_labels), (test_images, test_labels) = mnist.load_data()

train_images = train_images.reshape((60000, 28*28))
train_images = train_images.astype(‘float32’) / 255

test_images = test_images.reshape((10000,28*28))
test_images = test_images.astype(‘float32’) /255

network = models.Sequential()
network.add(layers.Dense(512, activation=‘relu’, input_shape=(28*28,)))
network.add(layers.Dense(10, activation=‘softmax’))

network.compile(optimizer=‘rmsprop’,
loss = ‘categorical_crossentropy’,
metrics=[‘accurancy’])

network.fit(train_images, train_labels, epochs=5, batch_size=128)

Thank you!

chunduriv · December 27, 2022, 12:14pm

Here the problem is that train_labels has only one column and the model expects output to have 10 , so it is throwing ValueError: Shapes (None, 1) and (None, 10) are incompatible.

You can convert the data labels (i.e.train_labels and test_labels) to categorical values by performing one-hot encoding using tf.keras.utils.to_categorical as shown below

train_labels = tf.keras.utils.to_categorical(train_labels)
test_labels = tf.keras.utils.to_categorical(test_labels)

Second problem was typo in accuracy

Please refer to the working code below

import numpy as np
import tensorflow as tf
print(tf.__version__)
from tensorflow.keras.datasets import mnist
from tensorflow.keras import models
from tensorflow.keras import layers

(train_images, train_labels), (test_images, test_labels) = mnist.load_data()

train_images = train_images.reshape((60000, 28*28))
train_images = train_images.astype("float32") / 255

test_images = test_images.reshape((10000,28*28,1))
test_images = test_images.astype("float32") /255

# Convert the data labels to categorical values by performing one-hot encoding
train_labels = tf.keras.utils.to_categorical(train_labels)
test_labels = tf.keras.utils.to_categorical(test_labels)

network = models.Sequential()
network.add(layers.Dense(512, activation="relu", input_shape=(28*28,)))
network.add(layers.Dense(10, activation="softmax"))

network.compile(optimizer="adam",loss="categorical_crossentropy" ,metrics=["accuracy"])
network.fit(train_images, train_labels, epochs=5, batch_size=128)

Output:

@benjsce,

It seems to be an issue with your tensorflow installation.

Can you install it as suggested Get started with tensorflow-metal ?

Thank you!

benjsce · December 28, 2022, 10:22am

I have already downloaded Tensorflow by this way. I uninstall and install again and I have the same results. I did same for python and I checked Python and Tensorflow version. All it right but Tensorflow doesn’t work.

Thank you

chunduriv · December 28, 2022, 10:40am

@benjsce,

Here the issue with Apple M1 and not with Tensorflow.

Could you please post this issue in the Apple developer forum Apple Developer Forums for quick assistance.

Thank you!
