yolov3AttributeError: 'NoneType' object has no attribute 'shape'

引用\[1\]:ValueError: Input 0 of layer conv2d is incompatible with the layer: expected ndim=4, found ndim=2. Full shape received: \[None, 784\]。这个错误提示表明在卷积层的输入维度与期望的维度不匹配。卷积层期望的输入维度是4维，但实际输入的维度是2维。可能的原因是输入数据的形状不正确，需要将其转换为4维张量。\[1\]

引用\[2\]:问题就出在加载权重（参数）文件的地方，加载权重命令load_weights前要先build一下，结果就build出这么一个错误：Exception ignored in: <bound method _RandomSeedGeneratorDeleter.__del__ of <tensorflow.python.data.ops.dataset_ops._RandomSeedGeneratorDeleter object at 0x7f363100d4e0>> Traceback (most recent call last): File "/usr/local/lib/python3.6/dist-packages/tensorflow_core/python/data/ops/dataset_ops.py", line 3462, in __del__ AttributeError: 'NoneType' object has no attribute 'device'。这个错误提示表明在加载权重文件之前需要先构建模型，否则会出现'NoneType' object has no attribute 'device'的错误。需要确保在加载权重之前已经正确构建了模型。\[2\]

引用\[3\]:最后我无意间发现了这样的Warning提示：\[1,0\]<stderr>:2020-06-30 08:34:47.818137: W tensorflow/core/framework/cpu_allocator_impl.cc:81\] Allocation of 376320000 exceeds 10% of system memory. \[1,0\]<stderr>:2020-06-30 08:34:49.030225: W tensorflow/core/framework/cpu_allocator_impl.cc:81\] Allocation of 188160000 exceeds 10% of system memory. 这个警告提示表明在分配内存时超过了系统内存的10%限制。可能的原因是模型或数据的大小超过了系统内存的限制。可以尝试减小模型的规模或者使用更大的内存来解决这个问题。\[3\]

问题:yolov3AttributeError: 'NoneType' object has no attribute 'shape'
回答: 这个错误提示表明在yolov3模型中出现了'NoneType' object has no attribute 'shape'的属性错误。可能的原因是某个变量或张量的值为None，而None对象没有shape属性。需要检查代码中相关变量或张量的赋值情况，确保它们不为None。另外，还可以尝试使用断点调试来定位具体出错的位置，以便更好地解决这个问题。
