Question

我正在尝试使用tf.train.import_meta_graph("./name.ckpt-1.meta")加载经过训练的网络“ name.ckpt-1.meta”的元图但出现以下错误：

Traceback (most recent call last):

    op_def = op_dict[node.op]
KeyError: 'ImageProjectiveTransformV2'

我不明白原因，在其他地方也没有看到相同的东西，我不确定是由于tensorflow版本还是其他原因。

Answer 1

我找到了解决方案；这是因为版本不匹配。就保存图形等而言，新版本的tensorflow与旧版本不匹配。如果我们使用旧版本保存检查点，则应使用正确的版本（首选相同版本）加载元图或冻结图。

通过import_meta_graph加载元图时出现ImageProjectiveTransformV2错误
