具有nVIDIA GEFORCE 920M GPU的Windows 10 Intel Core i3处理器上的Tensorflow安装

Question

我正在尝试按照此处的说明进行安装

我有一个兼容的nVIDIA GEFORCE 920M GPU和CRUD DNN工具包以及驱动程序都安装在系统上。 当我在python程序上执行步骤以在GPU上测试tensorflow安装时：

import tensorflow as tf
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

我得到的输出是：

>>> sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

The TensorFlow library wasn't compiled to use SSE instructions, but these 
are available on your machine and could speed up CPU computations.

The TensorFlow library wasn't compiled to use SSE3 instructions, but these

The TensorFlow library wasn't compiled to use SSE4.1 instructions, but these

我向您指出的问题是：

1. 在安装所有库和工具包而没有错误时，为什么仍未检测到nVIDIA GPU？

2. 为什么输出中显示“未编译TensorFlow库以使用SSE4.1指令，但是这些指令在您的计算机上可用，并且可以加速CPU计算”，我该如何纠正？

3. 请逐步解决。 没事

预先感谢您的回答。

Answer 1

好的，我的答案很明确：

Why is the nVIDIA GPU not getting detected when all librariries and toolkits are installed without errors?

回答：转到NVidia GEFORCE应用程序并更新驱动程序，然后将开始检测到库并且错误将消失。

Why is it the output saying "TensorFlow library wasn't compiled to use SSE4.1 instructions, but these are available on your machine and could speed up CPU computations" and how do i rectify this?

回答：完成上述更新后，TensorFlow库将停止提供SSE错误。 这样可以解决您的问题。

Please give a step by step solution. None other.

回答：鉴于以上所述，它对我有用。
