conda 或者 pip 安装包时报错，提示ModuleNotFoundError: No module named 'tqdm.auto'，要求安装tqdm包。
出现该报错的原因是python 包tqdm无故损坏。tqdm是一个报告python安装进度条的包，只要涉及到新包的安装或者旧包的更新都依赖该包。

这种状态下，即使按照提示用pip 或者conda 安装tqdm都会出现以上同样的报错，这个时候只有通过安装下载tqdm安装包（以这个版本为例 https://files.pythonhosted.org/packages/a8/4b/29b4ef32e036bb34e4ab51796dd745cdba7ed47ad142a9f4a1eb8e0c744d/tqdm-4.67.1.tar.gz）
下载后再pip3 install tqdm-4.67.1.tar.gz
就可以修复该问题。
