Tensorflow Deprecation Warnings

[siferati]

I get a bunch of tensorflow deprecation warnings when running PPO2 (haven't tried with other algorithms).

WARNING:tensorflow:From /home/tirafesi/.local/lib/python3.6/site-packages/stable_baselines/common/tf_util.py:57: The name tf.ConfigProto is deprecated. Please use tf.compat.v1.ConfigProto instead.

WARNING:tensorflow:From /home/tirafesi/.local/lib/python3.6/site-packages/stable_baselines/common/tf_util.py:66: The name tf.Session is deprecated. Please use tf.compat.v1.Session instead.

WARNING:tensorflow:From /home/tirafesi/.local/lib/python3.6/site-packages/stable_baselines/common/policies.py:115: The name tf.variable_scope is deprecated. Please use tf.compat.v1.variable_scope instead.

WARNING:tensorflow:From /home/tirafesi/.local/lib/python3.6/site-packages/stable_baselines/common/input.py:25: The name tf.placeholder is deprecated. Please use tf.compat.v1.placeholder instead.

WARNING:tensorflow:From /home/tirafesi/.local/lib/python3.6/site-packages/stable_baselines/common/policies.py:562: flatten (from tensorflow.python.layers.core) is deprecated and will be removed in a future version.
Instructions for updating:
Use keras.layers.flatten instead.
WARNING:tensorflow:Entity <bound method Flatten.call of <tensorflow.python.layers.core.Flatten object at 0x7f00e3f98278>> could not be transformed and will be executed as-is. Please report this to the AutgoGraph team. When filing the bug, set the verbosity to 10 (on Linux, `export AUTOGRAPH_VERBOSITY=10`) and attach the full output. Cause: converting <bound method Flatten.call of <tensorflow.python.layers.core.Flatten object at 0x7f00e3f98278>>: AttributeError: module 'gast' has no attribute 'Num'
WARNING:tensorflow:From /home/tirafesi/.local/lib/python3.6/site-packages/stable_baselines/a2c/utils.py:156: The name tf.get_variable is deprecated. Please use tf.compat.v1.get_variable instead.

Instructions for updating:
Use tf.where in 2.0, which has the same broadcast rule as np.where
WARNING:tensorflow:From /home/tirafesi/.local/lib/python3.6/site-packages/stable_baselines/ppo2/ppo2.py:209: The name tf.train.AdamOptimizer is deprecated. Please use tf.compat.v1.train.AdamOptimizer instead.

I installed stable-baselines by pip3 install stable-baselines and tensorflow by pip3 install tensorflow.

Keras-Applications==1.0.8
Keras-Preprocessing==1.1.0
stable-baselines==2.8.0
tensorboard==1.14.0
tensorflow==1.14.0
tensorflow-estimator==1.14.0
