Я тестирую код в Google Colab.Похоже, что Google Colab запускает версию 2 Tensorflow по умолчанию:
[In:]
import tensorflow as tf
print(tf.__version__)
[Out:]
2.0.0-dev20190130
и что эта версия не требует быстрого выполнения:
[In:]
tf.enable_eager_execution()
[Out:]
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-5-ddf3115bdcc7> in <module>()
----> 1 tf.enable_eager_execution()
AttributeError: module 'tensorflow' has no attribute 'enable_eager_execution'
Я не смог найти документацию по TensorFlow 2Также я не мог запустить более старую версию TensorFlow:
[In:]
!pip install tensorflow==1.12.0
import tensorflow as tf
print(tf.__version__)
[Out:]

И этот поток из 5 месяцев назад предполагает, что мы не можем понизить версию Tensorflow.
Возможно ли этовключить активное исполнение в Google Colab?
