导入keras

Question

我正在尝试导入keras，代码返回了一个关于tensorflow的错误。

import numpy
import matplotlib.pyplot as plt
import pandas
import math
from keras.models import Sequential
from keras.layers import Dense

错误是这样说的：

Using TensorFlow backend.

Answer 1

似乎没有找到tensorflow。您需要安装tensorflow才能使用keras库。

如果您已经安装了tensorflow，请尝试卸载并重新安装。

    sudo pip3 uninstall tensorflow 
    pip3 install --upgrade tensorflow

您可以通过运行以下命令来验证安装：

python3 -c "import tensorflow as tf; print(tf.reduce_sum(tf.random.normal([1000, 1000])))"

Answer 2

此错误与TensorFlow相关。TensorFlow可能未安装或安装不正确。请检查TensorFlow安装
