python - 如何将张量转换为numpy数组matmul的结果

问题描述

我想将 fc1 张量转换为 numpy 数组。如何得到它？

fc1 = tf.reshape(conv1, [-1, weights['wd1'].get_shape().as_list()[0]])
fc1 = tf.matmul(fc1, weights['wd1'])

标签： python

解决方案

它会导致此错误

    fc1 = tf.reshape(conv1, [-1, weights['wd1'].get_shape().as_list()[0]])
    fc1 = tf.matmul(fc1, weights['wd1'])
    sess = tf.Session()
    fc1.eval(session=sess)
