Restrictions

Before model conversion, pay attention to the following restrictions:

• To convert a network model such as Faster R-CNN, YOLOv3, or YOLOv2 into an offline model compatible with the Ascend AI Processor, modify the .prototxt model file by referring to "A Specific Topic for Network Customization" in the ATC Instructions first.
• Dynamic shape input is not supported, for example, NHWC = [?, ?, ?, 3]. The dimension sizes must be static.
• Except constant operators, the quantity of input and output dimensions of operators at all layers in the model must not be 0.
• Only the operators listed in the Caffe & TensorFlow & ONNX & PyTorch Operator Support are supported, and the operator restrictions must be met.
