WIP tf 2.2+ migration about deeplabcut-core HOT 13 CLOSED

WARNING:tensorflow:From /Users/mwmathis/opt/anaconda3/envs/DLC-CPU/lib/python3.7/site-packages/tf_slim/layers/layers.py:1089: Layer.apply (from tensorflow.python.keras.engine.base_layer_v1) is deprecated and will be removed in a future version.
Instructions for updating:
Please use `layer.__call__` method instead.
WARNING:tensorflow:From /Users/mwmathis/opt/anaconda3/envs/DLC-CPU/lib/python3.7/site-packages/tensorflow/python/ops/resource_variable_ops.py:1666: calling BaseResourceVariable.__init__ (from tensorflow.python.ops.resource_variable_ops) with constraint is deprecated and will be removed in a future version.
Instructions for updating:
If using Keras pass *_constraint arguments to layers.
WARNING:tensorflow:From /Users/mwmathis/Documents/DeepLabCut-core/deeplabcutcore/pose_estimation_tensorflow/nnet/losses.py:38: to_float (from tensorflow.python.ops.math_ops) is deprecated and will be removed in a future version.
Instructions for updating:
Use `tf.cast` instead.
