解决conda环境下import TensorFlow失败的问题

问题描述

安装了anaconda的电脑，新建了一个名叫deeplearning的环境，在该环境下已经成功安装了tensorflow。
于是在终端打开python并执行代码

import tensorflow as tf
print(1)

除了提示

1

错误提示是代表没有安装TensorRT，暂时忽略，可以看出已经打印了1，已经安装成功。
但是运行juypter-notebook后，会提示

ModuleNotFoundError: No module named 'tensorflow'

原因

在新建环境下，没有安装juypter-notebook，导致运行的juypter-notebook实际上仍然是base环境下的，因此失败

解决

conda activate deeplearning
conda install nb_conda

这样就在deeplearning安装了juypter-notebook了。
问题解决。
