机器学习 keras+flask(或者Django)问题

keras在flask跑出现的问题

alueError: Tensor Tensor("dense_3/Sigmoid:0", shape=(?, 59), dtype=float32) is not an element of this graph.

原始代码

    X = img.reshape([1, 32, width, 1])
    
    y_pred = basemodel.predict(X)
    y_pred = y_pred[:, :, :]

解决方法:

在上面代码所在的py文件前面插入

import tensorflow as tf
global graph,model
graph = tf.get_default_graph()

然在把刚刚的代码改为

    X = img.reshape([1, 32, width, 1])

    with graph.as_default():
        y_pred = basemodel.predict(X)
    y_pred = y_pred[:, :, :]
