Question

在这里，我正在使用mask_rcnn进行对象检测。该代码正常运行，但现在出现以下错误。

代码：

Testing - 1
# 1 - 200 images testing
# Load a random image from the images folder
file_names = next(os.walk(IMAGE_DIR))[2]
i=0


for fn in file_names:

    #image = skimage.io.imread(os.path.join(IMAGE_DIR, random.choice(file_names)))
    i = i+1
    print(i)

    image = skimage.io.imread(os.path.join(IMAGE_DIR, fn))

    # Run detection
    results = model.detect([image], verbose=1)

    # Visualize results
    r = results[0]

    visualize.display_instances(image, r['rois'], r['masks'], r['class_ids'], 
                            class_names, r['scores'])

错误消息：

您必须检查CUDA + CUDNN + TensorFlow的版本是否正确（还要确保已安装所有版本。

下面提供了两个运行配置的示例

例如。 Cuda 10 + CuDNN 7.6.3 + TensorFlow 1.13 / 1.14可以工作。

Eg2 Cuda 9 + CuDNN 7.0.5 + TensorFlow 1.10有效

通常，当您安装了不兼容的TensorFlow / CuDNN版本时，会出现此错误。就我而言，这是当我尝试使用较旧的TensorFlow和较新版本的CuDNN时出现的。

（0）未知：无法获得卷积算法。这可能是因为cuDNN无法初始化
