标题: crnn模型onnx转rknn报错
环境: ubuntu 18.04 / rknn-toolkit 1.3.2 / pytorch 1.2.0　

crnn模型是pytorch训练的，转成onnx模型，然后尝试转成rknn模型，在加载onnx模型时报错：
E Catch exception when loading onnx model: ../netCRNN_rknn.onnx!
E Traceback (most recent call last):

E KeyError: ''

查询文档得知KeyError似乎是因为有op不支持，但是后面提示是空的，不知道是哪个op报错了，我把onnx的所有node都打印出来，统计了所有的op_type如下(onnx版本1.6.0)：
{'Concat', 'Relu', 'Reshape', 'Squeeze', 'MaxPool', 'Add', 'ConstantOfShape', 'Shape', 'Sub', 'Gather', 'Gemm', 'Conv', 'Transpose', 'LSTM', 'Mul', 'Div', 'Slice', 'Clip', 'BatchNormalization', 'Pad', 'Unsqueeze', 'Constant'}
不知道是哪个op不支持呢？

也尝试过直接pytorch模型转rknn,也是加载模型的时候报错了:

存onnx时，尝试把opset_version设置成9 试试。

作者: leok 时间: 2020-8-6 16:00
onnx版本确认切换到1.4.1

onnx版本确认切换到1.4.1

pytorch模型导出的时候onnx opset_version设置为9, onnx版本切换为1.4.1,最后还是报一样的错误。
导出onnx模型的时候代码设置：

torch.onnx.export(net, input, 'netCRNN_rknn.onnx', export_params=True, verbose=True, opset_version=9)
复制代码

onnx转rknn代码:

# Create RKNN object

    rknn = RKNN(verbose=True)



    # pre-process config

    print('--> config model')

    rknn.config(channel_mean_value='0 0 0 1', reorder_channel='0 1 2')

    print('done')



    # Load onnx model

    print('--> Loading model')

    ret = rknn.load_onnx(model='../netCRNN_rknn.onnx')

    if ret != 0:

        print('Load model failed!')

        exit(ret)

    print('done')
复制代码

onnx模型所有node的op_type如下:
{'Gather', 'Conv', 'Clip', 'LSTM', 'Gemm', 'Constant', 'Pad', 'Transpose', 'Add', 'Reshape', 'Slice', 'ConstantOfShape', 'Shape', 'Concat', 'BatchNormalization', 'Relu', 'MaxPool', 'Mul', 'Squeeze', 'Sub', 'Unsqueeze', 'Div'}
报错:
