我在运行应用时收到此错误消息。它在应用程序启动后几秒钟就崩溃了。

Answer 1

您必须将输出图转换为优化图或量化图。

首先，为转换构建适当的工具：

对于优化图，

bazel build tensorflow/python/tools:optimize_for_inference

对于量化图，

bazel build tensorflow/tools/quantization:quantize_graph

然后，将再训练的图表转换为所需的格式：

再培训 - ＆gt;优化

tensorflow/bazel-bin/tensorflow/python/tools/optimize_for_inference \
--input=train/output/flower_photos/retrained_graph.pb \
--output=train/output/flower_photos/optimized_graph.pb \
--input_names=Mul \
--output_names=final_result

优化 - ＆gt;量化

bazel-bin/tensorflow/tools/quantization/quantize_graph \
--input=train/output/flower_photos/optimized_graph.pb \
--output=train/output/flower_photos/rounded_graph.pb \
--output_node_names=final_result \
--mode=weights_rounded

如果从头开始创建图形，则必须使用适当的图形名称，输入/输出节点名称可能不同

Answer 2

看起来您的Android版本或移动CPU不支持Tensorflow JNI库。您可能需要检查Android版本和移动CPU。

推理期间出错：参数无效：未注册OpKernel以支持Op＆＃39; DecodeJpeg＆＃39;与这些attrs
