how did you install it ?
you must you Miniforge3 as stated in the guide, not the regular conda.
if pip install do not works just install it with conda install instead
The workaround doesn't work in a tf.function, this is a real problem.
I tried other alternative like :
randomgen = tf.random.Generator.from_non_deterministic_state()
#%%
for _ in range(10):
g2 = tf.random.get_global_generator()
x = g2.uniform((10,),(1,2))
y = g2.uniform((10,),(3,4))
tf.print(x)
tf.print(y)
But
NotFoundError: No registered 'RngReadAndSkip' OpKernel for 'GPU' devices compatible with node {{node RngReadAndSkip}}
. Registered: device='CPU'
[Op:RngReadAndSkip]
And obviously calling this in a tf.function will always generate the same sequence
tf.random.stateless_uniform((size,),(1,2),xmin,xmax,tf.float32)
this doesn't works too :
randomgen = tf.random.Generator.from_non_deterministic_state()
@tf.function
def MandelbrotDataSet(size=1000, max_depth=100, xmin=-2.0, xmax=0.7, ymin=-1.3, ymax=1.3):
global randomgen
x = randomgen.uniform((size,),xmin,xmax,tf.float32)
y = randomgen.uniform((size,),xmin,xmax,tf.float32)
Because of RngReadAndSkip again.
shape[114389,320] ? are you sure you're not doing something wrong here ?
It's a perfectly normal and harmless message on a M1.
I have it too and my model & code works just fine.

reformatting your code :
import tensorflow as tf
from tensorflow.python.compiler.mlcompute import mlcompute
tf.compat.v1.disable_eager_execution()
mlcompute.set_mlc_device(device_name='gpu')
print("is_apple_mlc_enabled %s" % mlcompute.is_apple_mlc_enabled())
print("is_tf_compiled_with_apple_mlc %s" % mlcompute.is_tf_compiled_with_apple_mlc())
print(f"eagerly? {tf.executing_eagerly()}")
print(tf.config.list_logical_devices())
it look like some seriously old code, just do this instead
import tensorflow as tf
print(tf.__version__)
physical_devices = tf.config.list_physical_devices('GPU')
tf.print(physical_devices)
ex :
2.7.0

systemMemory: 8.00 GB
maxCacheSize: 2.67 GB

See this post, this should help, you have exactly the same problem : https://developer.apple.com/forums/thread/696693
wrote a minimal use case, this used to generate 2 different series :
import tensorflow as tf
x = tf.random.uniform((10,))
y = tf.random.uniform((10,))
tf.print(x)
tf.print(y)
[0.178906798 0.8810848 0.384304762 ... 0.162458301 0.64780426 0.0123682022]

works fine on collab :
It also works fine if I disable GPU with :
tf.config.set_visible_devices([], 'GPU')
WORKAROUND :
g = tf.random.Generator.from_non_deterministic_state()
x = g.uniform((10,))
y = g.uniform((10,))
tf.print(x)
tf.print(y)
I'm still on Epoch 5, on a MacBook Air M1 2020, but it look fine too me. so far.
My other trainings run just fine too. look like you just got bad luck on this run ? What about the other intermediary result ? do they all look bad ?
edit : I also have some very bad result sometimes, weird. is there a problem with random generation ?
i have a model that heavily use random.uniform, I'll check.
EDIT again : I need to double check but random is broken in some situation
I upgraded to 12.1 today.
I just launched a DCGAN, I'll let you know.
BUT, I have other model in training (an autoencoder) and haven't noticed any difference since yesterday.
I've installed Tensorflow multiple time on Mac M1 using this guide https://developer.apple.com/metal/tensorflow-plugin/
Just follow it step by step, don't skip the miniforge3 installation, it is absolutely mandatory to install and use the one provided in the guide.
Tested on python 3.8 and 3.9. Tensorflow is not supported on 3.10 (yet)
This isn't unexpected, on any platform with any device. Sometime the CPU is faster than the GPU.
Sometime my M1 on my MacBook Air 13" is faster than my Nvidia Quadro, or a Tesla K80.
It depend on the workload.
It's not specific to TensorFlow metal.
To be 100% sure you disable the GPU in order to test :
tf.config.set_visible_devices([], 'GPU')
We really lack documentation indeed. I had weird case were cpu was faster than gpu too. ^^
I only have the M1 (non pro/max)
To fully disable the CPU I use this :
tf.config.set_visible_devices([], 'GPU')
call it first before doing anything else.
You might also want to display what device is used for what operation :
tf.debugging.set_log_device_placement(True))
It's very verbose and the 1st step is usually mostly cpu (function tracing).
From my experience too : don't use float16 (not faster) and don't use mixed_precision (it fallback to CPU), at least on my M1.
Give a try to this option too :
physical_devices = tf.config.list_physical_devices('GPU')
tf.config.experimental.set_memory_growth(physical_devices[0],True)
From my understanding and information I gathered here and there over time : the neural engine is inferior to the gpu in every aspect for training a TF model and is ... kind of useless to us, developper ? If I extrapolate from the information I found, it's only useful for the tiny model (per today's standard) like the Apple's OCR (eg : you can copy/paste written in image), speech recognition, touchpad gesture, etc ...
