问题汇总

序号	问题	原因	解决办法
1	ModuleNotFoundError: No module named 'torch'	缺少依赖包
2	RuntimeError: Unable to open /dev/urandom	应该还是缺陷问题，不能打开文件，导致运行时间出错。	修改文件的权限 chmod 777 /dev/urandom
3	ModuleNotFoundError: No module named '_bz2'	python下缺包	添加“”文件包 拷贝python3.6下的该类型包，并修改名字 scp /usr/lib/python3.6/lib-dynload/_bz2.cpython-36m-aarch64-linux-gnu.so 用户名@localhost:/usr/local/python3.7.5/lib/python3.7/lib-dynload/_bz2.cpython-37m-aarch64-linux-gnu.so
4	ImportError: libGL.so.1: cannot open shared object file: No such file or directory	缺少文件	若需要添加用户sudo权限，则root用户下执行添加权限操作： usermod libaoshan -G sudo 安装相关依赖： sudo apt-get install  libgl1-mesa-glx
5	ModuleNotFoundError: No module named '_lzma'	缺少包	https://zhuanlan.zhihu.com/p/404162713
6	Sorry, user libaoshan is not allowed to execute '/usr/bin/vim /usr/local/python3.7.5/lib/python3.7/lzma.py' as root on davinci-mini.	缺少执行权限
7	AttributeError: ‘Upsample‘ object has no attribute ‘recompute_scale_factor‘		https://blog.csdn.net/qq_42578742/article/details/123582773
8	ONNX: export failure: No module named 'onnx'	缺包	pip install onnx
9	/usr/local/python3.7.5/bin/python3.7: No module named onnxsim	缺包	pip install onnx-simplifier
	ModuleNotFoundError: No module named 'onnx.optimizer'	onnx包和onnx-simplifier版本不匹配	pip3 install skl2onnx pip install onnx==1.8.1 https://blog.csdn.net/sinat_38685910/article/details/119329283 或者使用源码来解决问题，安装onnx和如下包。 https://github.com/onnx/optimizer
