我访问了the tensorflow page,并按照Installing with Anaconda部分的说明进行操作。当我尝试验证我的安装时,我得到了以下错误

(C:\ProgramData\Anaconda3) C:\Users\nik>python

然后我试了

我的问题如下 - 我的主要问题是问题3:

  1. 我想在输入命令后验证安装 - activate tensorflow如上面的第二个命令块所示?
  2. 为什么我之后会收到多条指令 命令sess = tf.Session()
  3. 我可以在其中使用tensorflow吗? SPYDER gui?怎么样?我试过下面但是在SPYDER gui,但没有取得任何成功:(

    激活tensorflow

  4. 档案“”,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'
    

3 个答案:

答案 0 :(得分:2)

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 :不确定为什么有多条指令,但这是正常的,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

Q3 :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&#34; conda create -n tensorflow python = 3.5 anaconda&#34;

  2. 创建tensorflow环境
  3. 创建虚拟环境后,输入命令&#34;激活tensorflow&#34;

  4. 现在使用&#34; pip install tensorflow&#34;安装tensorflow。 (仅限CPU)或pip install tensorflow-gpu(用于GPU)。

  5. 现在转到安装anaconda的文件夹。

  6. 如果C:\ ProgramData \ Anaconda3是Anaconda根文件夹,那么转到&#34; C:\ ProgramData \ Anaconda3 \ envs \ test \ Scripts&#34;并打开spyder.exe。您应该能够在此环境中成功导入tensorflow。

答案 1 :(得分:0)

您应该从命令提示符处激活虚拟环境。激活后,您应该运行命令spyder,这将从您的虚拟环境中打开spyder gui

答案 2 :(得分:0)

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,然后通过键入“激活tensorflow”来激活tensorflow环境。然后键入spyder打开你的spyder gui。它主要解决问题。
