用conda创建好了paddle的虚拟环境，在官网直接粘贴了conda安装的语句，安装成功后激活paddle，输入python,然后import paddle.fluid，没报错，再然后 paddle.fluid.install_check.run_check()也没报错，甚至成功了，如下：

（paddle) C:\Users\ASUS>python

>>> import paddle.fluid

然后使用jupyter测试，报错了...

如下：

(paddle) C:\Users\ASUS>jupyter notebook

import paddle.fluid
paddle.fluid.install_check.run_check()

ModuleNotFoundError Traceback (most recent call last)
in
----> 1 import paddle.fluid
2 paddle.fluid.install_check.run_check()

ModuleNotFoundError: No module named 'paddle'

这一切到底是为什么啊！！！！！
