在ubuntu pip安装 datasets matplotlib pyarrow等包时 可能遇到如下报错：

网上搜到的其他解决方案都没解决我的问题，最终本人用的：
python -m pip install --upgrade pip
另外， 拿到一个新linux环境，最常安装和修改的东西 可以记下来，下次使用新环境按checklist操作 可以快速避坑。新增和修改配置文件 可以echo后重定向或sed之类。 一般拿到新环境后， centos需要安装的东西 包括但不限于如下； 如果新安装python版本，安装后需要更新的其他工具（例如setuptools, pip）和源的修改 都可以记下来依次执行，有时候忘了更新这些，后面可能要定位奇怪的安装问题，这样的定位有点浪费时间，可以避免的。 本人平时记录了centos的，ubuntu的没记，这不，忘记更新pip，ubuntu上就踩坑了(将来多装几次ubuntu再发出来)
yum -y update
yum -y install gcc
yum -y install zlib zlib-devel
yum -y install bzip2 bzip2-devel
yum -y install ncurses ncurses-devel
yum -y install readline readline-devel
yum -y install openssl openssl-devel
yum -y install openssl-static
yum -y install xz lzma xz-devel

yum -y install tk tk-devel
yum -y install libffi libffi-devel
yum -y install python-devel
yum -y install libevent-devel
yum -y install gcc gcc-c++
安装python3后，除了常用的库 还有：
pip3 install --upgrade pip
pip3 install --upgrade setuptools
pip3 install setuptools_scm
当然 使用标准化后的docker 也是OK的。不过基础环境 还是要准备一下。
