TensorFlow重新訓練的初始v3模型在Android上崩潰

Question

我已經使用我自己的數據集重新訓練了TensorFlow Inception v3模型，如本教程所述 。

現在我正在嘗試使用我的再培訓模型構建和運行TensorFlow Android示例 。 我按原樣從示例中構建了本機代碼，將模型（.pb）和標簽（.txt）文件復制到資產目錄並更改了TensorFlowImageListener.java的模型參數：

private static final int NUM_CLASSES = 5; // number of categories
private static final int INPUT_SIZE = 299;
private static final int IMAGE_MEAN = 128;
private static final float IMAGE_STD = 128;
private static final String INPUT_NAME = "Mul:0";
private static final String OUTPUT_NAME = "final_result:0";

但解析從資產加載的模型文件時應用程序崩潰：

PS我也試過像這樣使用tensorflow/python/tools/strip_unused.py （ 這里建議）：

bazel build tensorflow/python/tools:strip_unused && \
bazel-bin/tensorflow/python/tools/strip_unused \
--input_graph=some_graph_def.pb \
--output_graph=/tmp/stripped_graph.pb \
--input_node_names=Mul
--output_node_names=final_result

沒有幫助。

問題在於gradle壓縮資產文件導致模型解析失敗。 我禁用了.pb文件的壓縮：

aaptOptions { noCompress 'pb' }
