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,

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。
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。

解决方法:将图片报错到本地,将filepath的路径改为本地路径
img = Image.open('../images/pack.jpg')
