一： 打不开cmd/cmd闪退问题解决

1.win+R打开 regedit

2.在注册表找到 HKEY_CURRENT_USER\Software\Microsoft\Command Processor路径

3.在该路径下找到AutoRun，将数值改为空

可能原因：找到AutoRun 发现值是： if exist & if exist "D:\software\miniforge3\condabin\conda_hook.bat" "D:\software\miniforge3\condabin\conda_hook.bat"

可能是版权问题删除anaconda后安装miniforge3默认导致的。

二：pyspark环境打包问题解决：

pysaprk需要python3环境，conda建环境，python39环境，报如下错误：

"/data08/hadoop/yarn/local/usercache/dms/appcache/application_1719854044076_229309/container_e217_1719854044076_229309_02_000001/pyspark.zip/pyspark/cloudpickle.py", line 127, in _make_cell_set_template_code TypeError: an integer is required (got type bytes)

网上搜是版本问题，python版本或者pyspark版本。

新建环境，python37环境，解决了。

三：pip安装包各种问题

docx包：

pip install docs -i https://pypi.tuna.tsinghua.edu.cn/simple/

运行 报错：

ModuleNotFoundError                       Traceback (most recent call last)
Cell In[8], line 1
----> 1 import docx  
      2 import os  
      3 import json  

File d:\software\miniforge3\envs\tf1.14_py39\lib\site-packages\docx.py:30
     27 except ImportError:
     28     TAGS = {}
---> 30 from exceptions import PendingDeprecationWarning
     31 from warnings import warn
     33 import logging

ModuleNotFoundError: No module named 'exceptions

解决办法：

pip  uninstall docx

pip  install python-docx -i https://pypi.tuna.tsinghua.edu.cn/simple/

即可。

四：windows同时安装gitlab和github多个git

一个用来公司用。一个用来自己的demo用。

Windows上同时配置GitHub，Gitlab，Gitee（码云）三种开发环境_window搭建码云类似的-CSDN博客

https://blog.csdn.net/kyyius/article/details/116232389

参考以上2篇文章。

补充点：

1.链接1提到全局配置要删除，亲测不用删除也可以，github和gitlab都可以正常提交任务。

2.关键是.ssh/下新建confit文件。配置不同的github和gitlab的选择。

3.默认是.ssh/路径下生产私钥和公钥，如果换个新的名字，在哪个路径下生成，秘钥就落到哪个路径下。

五：github相关

1.访问限制

有时候国内打不开github，加上kk前缀即可快速打开。 

kkgithub.com/langgenius/dify

2.vscode文本编辑器在线打开

github1s.com 

github.dev 

六：python web

1.flask

我部署的flask服务，别人调用http接口请求我的服务，我在我的请求里接收参数，再请求别人的requests.post 调用另一个的服务2次。本地启动flask，流程都是通的，但是部署到docker里如果是请求参数是短文本，都正常，如果是长文本，则会报错。

Traceback (most recent call last):

  File "/usr/local/lib/python3.9/site-packages/gunicorn/workers/base.py", line 204, in handle_abort
    sys.exit(1)

发现是 下面这行命令报错。

# 启动容器时运行的命令

 CMD gunicorn -w 4 --bind 0.0.0.0:5000 app:app

gunicorn是多进程启动。这是启动 Gunicorn 服务器的命令，

• -w 6：-w 或 --workers 选项后面跟的数字表示工作进程的数量。在这个例子中，6 表示 Gunicorn 将启动 6 个工作进程来处理传入的请求。工作进程的数量通常取决于服务器的 CPU 核心数和预期的负载。

本地启动没问题，线上docker里部署短文本请求没问题。长文本单次requests.post没问题。但是我这里有2次的requests.post 就报上面的问题了。 

解决办法：

dockerfile 里这样启动，不用多进程了。 

CMD ["sh", "-c", "python  app.py"]

可能的原因是的多线程并发这块，flask的天然不太好。 

看到这句话：

   ```

如果你追求高性能、异步编程和类型安全，FastAPI可能是更好的选择。如果你注重简洁性、灵活性和成熟的生态系统，Flask是一个可靠的选择
