无法为deepLabv3+inferen指定或混淆矩阵

Question

我在评估deeplabv3+模型的冻结推理图的平均分数。 在评估平均IOU分数时，我扩展了冻结的IOU图，遇到了以下错误：

When I tried to break it down to confusion _matrix and calculate mean_IOU later, but the following error was thrown:

此错误与上一个错误类似。 我试过CPU和GPU（CUDA9.0和CUDNN7.1），都是在Tensorflow版本1.11和1.12的Windows上，但是错误没有改变。你知道吗
