Question
I am running this simple code on Spyder 3.3 with Python 3.7 and Tensorlow 2.0:
import tensorflow as tf
print(tf.__version__)
When I try to run it again in the same IPython console, I get the following error:
File "/home/rodrigo/.local/lib/python3.7/site- packages/tensorflow_core/python/eager/monitoring.py", line 121, in init self._metric = self._metric_methods[self._label_length].create(*args)
AlreadyExistsError: Another metric with the same name already exists.
If I close the IPython console, and then open it again, it works fine. I am getting this error in every code that imports Tensorflow. Does anyone know how to solve this?
System configuration:
- Ubuntu 19.04
- Spyder 3.3.2
- Python 3.7.3
- IPython 5.8.0
- TensorFlow 2.0.0-rc2
Answer
Tensorflow constructs singletons as side effects during import. Importing twice results in the singletons being created again, which is not supported. Please never import twice.
