It seems it didn't get much attention since it's lost in another thread. tf.random is broken since 12.1. 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] [0.178906798 0.8810848 0.384304762 ... 0.162458301 0.64780426 0.0123682022] works fine on collab, worked on 12.0, 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,))
