在Windows anaconda中安装tensorflow - 并使用Spyder GUI运行它

Posted 2021-04-10

我访问了the tensorflow page并遵循了Installing with Anaconda部分的指示。当我尝试验证我的安装时，我遇到了以下错误

然后我试过了

我的问题如下 - 我的主要问题是问题3：

1. 我想在键入命令 - activate tensorflow之后验证安装，如上面的第二个命令块所示？
2. 为什么我在命令sess = tf.Session()后得到多个指令？
3. 我可以在SPYDER gui中使用tensorflow吗？怎么样？我试过下面但是在SPYDER gui，但没有取得任何成功:( 激活张量流

文件“”，第1行

    activate tensorflow
                      ^

SyntaxError: invalid syntax


import tensorflow as tf

Traceback (most recent call last):


  File "<ipython-input-2-41389fad42b5>", line 1, in <module>
    import tensorflow as tf


ModuleNotFoundError: No module named 'tensorflow'

答案

Q1：是的，您需要激活虚拟环境以导入tensorflow，因为您已在虚拟环境中安装了tensorflow。

Q2：不确定为什么有多个指令但是这是正常的并且内置在tensorflow中。您可以通过在启用SIMD指令的情况下自行构建张量流来避免这些问题。 https://www.youtube.com/watch?v=ghv5fbC287o

问题3：您需要在创建虚拟环境时更改第一步。使用以下命令创建虚拟环境{conda create -n tensorflow python = 3.5 anaconda}。

Q3的详细答案如下：

1. 使用“conda create -n tensorflow python = 3.5 anaconda”创建tensorflow环境
2. 创建虚拟环境后，输入命令“activate tensorflow”
3. 现在使用“pip install tensorflow”（仅限CPU）或pip install tensorflow-gpu（用于GPU）安装tensorflow。
4. 现在转到安装anaconda的文件夹。
5. 如果C： ProgramData Anaconda3是Anaconda根文件夹，则转到“C： ProgramData Anaconda3 envs test Scripts”并打开spyder.exe。您应该能够在此环境中成功导入tensorflow。

另一答案

您应该从命令提示符处激活虚拟环境。一旦激活，你应该运行命令spyderwhich将打开你的虚拟环境中的spyder gui

另一答案

问题是你的张量流安装在conda环境中。因此，首先以管理员身份打开conda提示符，然后键入“activate tensorflow”激活tensorflow环境，然后键入spyder打开你的spyder gui。它主要解决问题。
