导入 tensorflow 时出错“AlreadyExistsError: 另一个同名指标已经存在." [英] Error importing tensorflow "AlreadyExistsError: Another metric with the same name already exists."

问题描述

我正在使用 Python 3.7 和 Tensorlow 2.0 在 Spyder 3.3 上运行这个简单的代码:

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__)

当我尝试在同一个 IPython 控制台中再次运行它时，出现以下错误:

When I try to run it again in the same IPython console, I get the following error:

文件/home/rodrigo/.local/lib/python3.7/site-packages/tensorflow_core/python/eager/monitoring.py"，第 121 行，initself._metric = self._metric_methods[self._label_length].create(*args)

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:已存在另一个同名指标.

AlreadyExistsError: Another metric with the same name already exists.

如果我关闭 IPython 控制台，然后再次打开它，它工作正常.我在导入 Tensorflow 的每个代码中都收到此错误.有人知道如何解决这个问题吗?

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?

系统配置:

• Ubuntu 19.04
• Spyder 3.3.2
• Python 3.7.3
• IPython 5.8.0
• TensorFlow 2.0.0-rc2

推荐答案

Tensorflow 在导入过程中构建单例作为副作用.导入两次会导致再次创建单例，这是不受支持的.请不要导入两次.

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.
