Eager 模式下操作会立刻执行并返回实际值在这里 tfTensor 对象会是一个实际值而不是 graph 模式下的 Tensor 结构这个 Tensor 结构主要包含了三个属性名字维度和类型而且只有运行 graph 的时候Tensor 才会有真实的值. Fit model with labels in range 05 Epoch 15 2020 - 0s 25msstep - loss.

TensorFlow是一个基于数据流编程dataflow programming的符号数学系统被广泛应用于各类机器学习machine learning算法的编程实现其前身是谷歌的神经网络算法库DistBeliefTensorflow拥有多层级结构可部署于各类服务器PC终端和网页并支持GPU和TPU高性能数值计算被广泛应用于谷歌内部的产品.
Calculate Loss for both TRAIN and EVAL modes loss tflossessparse_softmax_cross_entropylabelslabels logitslogits The final step of the TensorFlow CNN example is to optimize the model that is to find the best values of the weights. 如果你在使用 lossnumpy 等类似的语句 Tensor object has no attribute numpy的时候 原因可能有两个 第一个是TensorFlow的版本问题要TensorFlow114以上版本才有所以就解决方案就是升级TensorFlow到114以上版本 具体语句为pip install tensorflow版本号 第二个原因如果你升级了以后还是报错那么就添加以下语句tf. The solution for me was using tflossessparse_softmax_cross_entropyy logits instead of my own implementation of Safe Softmax using tfnnSoftmax Eduardo Reis.
