在centos7上运行paddlepaddle 需要用到paddlehub，安装完paddlehub后使用hub命令提示以下报错
[root@localhost ~]# hub

这里提示缺少“tqdm.contrib”模块，但是我在python中就可以直接import进来，并没有报错

以下内容由CHATGPT及阿里嘎多学长共同生成、有用望采纳：
可以尝试在CentOS 7上使用以下命令安装tqdm模块：
sudo yum -y install python3-tqdm
如果上述命令不行，可以尝试升级pip并使用pip安装tqdm模块：
sudo python3 -m pip install --upgrade pip
sudo python3 -m pip install tqdm
如果还是无法解决问题，可以考虑在Python中查看tqdm模块的安装路径，并将其添加到系统环境变量中：
python3 -c "import tqdm; print(tqdm.__file__)"
然后将输出的路径添加到系统环境变量中：
export PYTHONPATH=$PYTHONPATH:/path/to/tqdm
或者将其添加到Python模块搜索路径中：
echo "/path/to/tqdm" >> /usr/local/python3/lib/python3.6/site-packages/custom.pth
其中，/path/to/tqdm为tqdm模块的安装路径。
该回答通过自己思路及引用到GPTᴼᴾᴱᴺᴬᴵ搜索,得到内容具体如下：
根据报错信息，可以看到在PaddleHub命令中缺少了'tqdm.contrib'模块，但是在Python 3.6中却可以成功导入该模块。这可能是因为在PaddleHub中使用的Python环境与您在Python 3.6中使用的环境不同导致的。
解决该问题的方法是在PaddleHub环境中安装'tqdm'模块及其依赖项。
可以使用以下命令在PaddleHub环境中安装'tqdm'模块：
pip install tqdm
如果您在安装时遇到了权限问题，可以在命令前加上'sudo'：
sudo pip install tqdm
如果您使用的是conda环境，可以使用以下命令安装'tqdm'模块：
conda install tqdm
安装完成后，尝试再次使用PaddleHub命令，应该就可以正常运行了。如果还有其他问题，可以提供更多的错误信息和代码，以便更好地帮助您解决问题。
