一、OSError: [WinError 127] 找不到指定的程序。 Error loading "D:\my_ruanjian\conda-myenvs\deeplearning\lib\site-packages\torch\lib\caffe2_detectron_ops.dll" or one of its dependencies.

报错：

原因：是由于torch与torchaudio版本不匹配导致的

解决方法：

二、proj.db contains DATABASE.LAYOUT.VERSION.MINOR = 0 whereas a number >= 2 is expected. It comes from another PROJ installation

场景：最近发现一个问题，在使用GDAL+Python进行开发时，代码总报如下错误：

原因：从错误里可以看出，GDAL在调用PROJ时，遇到了版本冲突的问题。

GDAL底层使用PROJ的库，进行坐标系相关的转换；
PostgreSQL数据库插件PostGIS 也是使用了PROJ；

两个工具安装的PROJ库版本不一样，且在计算机环境变量里相互干扰。

解决方法：找到对应自己的python包的安装地址，

复制代码

import os
# 对应自己的python包的安装地址
os.environ['PROJ_LIB'] = r'D:\my\python-pycharm\python-envs\pathplanning\Lib\site-packages\pyproj\proj_dir\share\proj'

然后运行代码时，就不报错误了。

三、 There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.tuna.tsinghua.edu.cn', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: EE certificate key too weak (_ssl.c:1002)'))) - skipping

报错：使用pip install 某个包的时候报错

原因分析：无法访问到https://pypi.tuna.tsinghua.edu.cn/simple/pip，SSL证书认证问题。

解决方法：此时需要获得 ssl证书的认证，需要在原来的安装命令后增加：-i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com （也可换其他源），这是阿里源 --trusted-host mirrors.aliyun.com 这是为了获得ssl证书的认证。

四、Max retries exceeded with url: /pkgs/main/linux-64/current_repodata.json (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: EE certificate key too weak (_ssl.c:1002)')))

报错：在我设置好国内源之后，用conda创建虚拟环境，下载python版本时出现以下错误

原因分析：从错误信息看是无法获取资源https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/linux-64/current_repodata.json, 进而通过wget命令尝试获取该资源

解决方法：在命令行中输入conda config --set ssl_verify false修改设置，或者在文件~/.condarc末尾添加一行ssl_verify: false（有则修改即可），把清华源那些链接里的https改成http。

五、ImportError: cannot import name 'clock' from 'time' (unknown location)

报错：

原因：这个问题通常出现在Python 3.8版本之后，因为在Python 3.8中，time模块中的clock()函数被废弃，取而代之的是perf_counter()函数和process_time()函数。

解决方法：那么，解决这个问题的方法就是使用perf_counter()函数或process_time()函数替代clock()函数。这两个函数分别用于性能计数和进程计时，能够更准确地测量时间。

复制代码

from time import process_time as timer

timer()

六、UnidentifiedImageError: cannot identify image file <_io.BytesIO object at 0x00000200EDD9BEA0>

报错：

原因：这个链接是一张图片，但是python读取不到图片，报错了，可能是图片的问题导致读取不出来。

复制代码

https://images.mulberry.com/i/mulberrygroup/RL5792_000N651_L/small-hampstead-deep-amber-small-classic-grain-ayers/small-hampstead-deep-amber-small-classic-grain-ayers?v=3&w=304

解决方法：将图片报错到本地，将filepath的路径改为本地路径

复制代码

img = Image.open('../images/pack.jpg')
