【问题描述】：

我正在运行 android 的 Softbank Robotics 的 Pepper 1.8 (QiSDK 1.7.5) 上运行定制的 Tensorflow Lite 模型。

我成功捕获图像，将其转换为bitmap，然后将其转换为TensorImage。 之后我构建ObjectDetector 并运行它。下面你可以看到我的检测功能：

private void runDetection(Bitmap pictureBitmap) throws IOException 
    TensorImage image = TensorImage.fromBitmap(pictureBitmap);
    ObjectDetector.ObjectDetectorOptions options = ObjectDetector
            .ObjectDetectorOptions.builder()
            .setMaxResults(5)
            .setScoreThreshold(0.5F)
            .build();

    ObjectDetector detector = ObjectDetector
            .createFromFileAndOptions(this, "detect_2_5.tflite", options);

    List results = detector.detect(image);

Tnesorflow 被初始化，但之后我得到一个致命的异常。这是我的错误日志：

我将不胜感激。

【参考方案1】：

你需要删除以下依赖

'org.tensorflow:tensorflow-lite-support:0.1.0'

org.tensorflow:tensorflow-lite-task-vision:0.0.0-nightly-SNAPSHOT 使用更新版本的支持库 (0.2.0 +)，它作为 ColorSpaceType.getValue() 方法。但它会被support:0.1.0 覆盖。

还有org.tensorflow:tensorflow-lite-metadata:0.1.0没用，可以去掉。

【讨论】：

谢谢王路，成功了，我更喜欢用org.tensorflow:tensorflow-lite-task-vision:0.2.0而不是org.tensorflow:tensorflow-lite-task-vision:0.0.0-nightly-SNAPSHOT吗？

我实际上需要org.tensorflow:tensorflow-lite-metadata:0.1.0，因为detect.java 正在使用它。

org.tensorflow:tensorflow-lite-task-vision:0.2.0 比nightly-SNAPSHOT 更稳定，我推荐它用于生产。
