RK1808 S0 计算棒问题汇总 - Toybrick

如下错误：
[toybrick@rk1808 rockx_py]$ python3 rockx_object_detection.py
Traceback (most recent call last):

AttributeError: /usr/local/lib/python3.6/site-packages/rockx/sdk/rockx-rk1808-Linux/lib64/librockx.so: undefined symbol: rockx_carplate_align_v2

2. RockX-SDK-V1.4.4 里有个 command_line_demo 文件夹，不知道做什么用？没有找到有地方进行说明。
3.回退到 RockX-SDK-V1.2.0后，运行 python3 rockx_object_detection.py 依然提示undefined symbol: rockx_carplate_align_v2
4.onnx转换为rknn模型时，提示错误，也不知道哪里问，是否有QQ群之类的官方支持呢？
