tf.VERSION 始终是 1.6.0 即使我安装了最新版本

Question

请帮我解决这个问题-我使用Google的Colaboratory来运行 tensor_hub example Text classification with TF-Hub，它需要1.7以上的版本。 0，但是我安装的版本是1.8.0.

# Install the latest Tensorflow version.
!pip install --quiet "tensorflow>=1.7"
# Install TF-Hub.
!pip install tensorflow-hub

import tensorflow as tf
import tensorflow_hub as hub
import matplotlib.pyplot as plt
import numpy as np
import os
import pandas as pd
import re
import seaborn as sns

Answer 1

您可能需要重新启动运行时。

menu > Runtime > Restart runtime...

Answer 2

好消息：TF 1.7 现在默认可用。 :)

您遇到的根本问题只是 python 在 sys.modules 中缓存加载的模块——重新导入模块在您重新启动进程之前不会获取新版本，因为Korakot 指出。

tf.VERSION 始终是 1.6.0 即使我安装了最新版本

tf.VERSION is always 1.6.0 even though I installed the latest version
