pip-21.3.1版本安装报错

pip-21.3.1$ python setup.py install
  File "setup.py", line 7
    def read(rel_path: str) -> str:

重新安装pip-20.3.4版本

pip-20.3.4$ python setup.py install
Traceback (most recent call last):
  File "setup.py", line 8, in 
    from setuptools import find_packages, setup
importError: No module named setuptools

下载setuptools：https://www.cnblogs.com/asseye/p/12147094.html

cd setuptools-33.1.1
python setup.py install

安装完成之后再继续安装pip
或者直接用指令安装

sudo apt install python3-pip

最后
sudo -H pip install -U jetson-stats

查看的时候好多cpu显示off

还查看到运行时gpu使用率是99%
nx还自带流查看cpu和gpu使用率的工具，使用方法如下
