导入tensorflow.contrib.slim时如何解决UnicodeDecodeError

Question

我在导入 tensorflow.contrib.slim 时遇到了这个问题

import tensorflow.contrib.slim as slim

回溯是：

Answer 1

为Tensorflow 1 和Tensorflow 2 提供解决方案。

将Tensorflow 1 旧版本升级到1.14 和1.15-rc0 等稳定版本将解决您的问题。

张量流 1：

安装：

pip install tensorflow==1.15

进口：

import tensorflow.contrib.slim as slim

张量流 2：

由于在 Tensorflow 2 中，slim 被移动到不同的存储库，您需要单独安装它并像下面这样导入它。

安装：

pip install --upgrade tf_slim 

进口：

import tf_slim as slim
