Does tensorflow_addons conflict with tensorflow?

Question

I'm able to run an ANN model using tensorflow and keras as below:

import tensorflow as tf
from keras.models import Sequential 
from keras.layers import Dense
firstModel = Sequential()

Since I need to use RSquared metric (R2), I installed tensorflow_addons to my conda environment too. Now, even without importing tensorflow_addons I get a long error message on the import tensorflow as tf line, the last line says:

AlreadyExistsError: Another metric with the same name already exists.

How can I fix the issue? Is there another way to get R2 rather than : import tensorflow_addons from tensorflow_addons.metrics import RSquare
