Question

我正在使用 Jetson Xavier NX 来运行由 [Segmentation][1] 创建的分段。这些是我正在使用的库的版本张量流 - 1.15.4 keras - 2.1.5 蟒蛇 - 3.6.9

但是，当我运行我的程序时，出现以下错误

2021-06-14 20:30:53.671609: W tensorflow/core/framework/op_kernel.cc:1651] OP_REQUIRES failed at random_op.cc:76 : Resource exhausted: OOM when allocating tensor with shape[3,3,128,128] and type float on /job:localhost/replica:0/task:0/device:GPU:0 by allocator GPU_0_bfc

这是我的代码

import cv2
# Load a random image from the images folder
file_names = next(os.walk(IMAGE_DIR))[2]
image = skimage.io.imread("/sample_images/sample3.jpg")

# 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'])
cv2.imwrite("hi.jpg",image)

我在 aws ec2 上运行了相同的程序。唯一的区别是那里的 tensorflow 版本（我使用了 1.8.0 gpu）并且运行良好。是不是tensorflow版本导致的错误？

编辑我已将此添加到代码的开头，如某些 github 问题所示

import tensorflow as tf
config = tf.ConfigProto()
config.gpu_options.allow_growth = True
sess = tf.Session(config=config)

我仍然收到警告并且没有退出

2021-06-15 12:58:33.680104: W tensorflow/core/common_runtime/bfc_allocator.cc:305] Garbage collection: deallocate free memory regions (i.e., allocations) so that we can re-allocate a larger region to avoid OOM due to memory fragmentation. If you see this message frequently, you are running near the threshold of the available device memory and re-allocation may incur great performance overhead. You may try smaller batch sizes to observe the performance impact. Set TF_ENABLE_GPU_GARBAGE_COLLECTION=false if you'd like to disable this feature.

我如何检查我的 gpu 是否正确分配？ [1]：https://github.com/matterport/Mask_RCNN
