Trivial Tensorflow setup crashes on AWS DL1 Ubuntu 20.04 LTS

When running a simple tensorflow script:

import tensorflow as tf
from habana_frameworks.tensorflow import load_habana_module
model = tf.keras.models.Sequential([
    tf.keras.layers.Flatten(input_shape=(28, 28)),

I get the following error:

I’m running without docker with the binary distribution.

Hi @curufinwe, we suspect that the habanalabs-firmware 1.1.0-614 package is missing, please run 1) dpkg -l | grep habanalabs-firmware 2) dpkg -l | grep habanalabs-dkms commands to confirm this.

The missing habanalabs-firmware package was indeed the root cause of the problem. After installing that package the tensorflow example could run. Thank you!


That’s great, good luck.
