从目标C中的Bundle读取mlmodel

我试图读取一个.mlmodel文件来编译并在我们的库中使用它。我正在测试库,但我不能读取文件和编译它。。。我不知道为什么。我正在使用这两个函数(都不起作用)

-(NSString*) FilePathForResourceName:(NSString*) name  forExtension:(NSString*) extension {
    NSBundle *bundle = [NSBundle bundleForClass:[self class]];
    NSString* file_path = [bundle pathForResource:name ofType:extension];
    return file_path;
}


-(NSString*) FilePathForMainBundleResourceName:(NSString*) name  forExtension:(NSString*) extension {
    NSBundle *main = [NSBundle mainBundle];
    NSString* file_path = [main pathForResource:name ofType:extension];
    return file_path;
}

- (void)testShouldAnalyseCorrectlyWithDetectionBicycles {
    NSString* image_path = [self FilePathForResourceName:@"bicycles" forExtension:@"jpg"];
    NSString* labels_path = [self FilePathForResourceName:@"coco_labels_list" forExtension:@"txt"];
    NSString* network_path = [self FilePathForResourceName:@"ssd_mobilenet_feature_extractor" forExtension:@"mlmodel"];
    CoreMLLib* lib = [[CoreMLLib alloc] init:network_path forLabel:labels_path];
    [lib run:image_path];
}

我认为,它正确地添加到了项目中的文件中(对于目标测试和库):

中的值参数 FilePathForResourceName文件路径

• 名称->ssd\u mobilenet\u feature\u extractor
• 文件路径->无
• “/Users/joan/Library/Developer/Xcode/DerivedData/draagu ios tensorflow lib hglbppvrarumdfwgjoebcuesar/Build/Products/Debug iphonesimulator/draagu ios tensorflow-libTests.xctest测试“0x00007f7f1fc2cb40
