使用conda安装paddleocr

 conda env  remove --name paddle_env

conda create --name paddle_env2 python=3.12 -c conda-forge

conda activate paddle_env2

#conda install -c conda-forge cudatoolkit=11.7 

#conda install  -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/   paddlepaddle-gpu==2.6.1

很奇怪，把下面的命令拆分成上面的2条命令，竟然安装失败

conda install  -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/   paddlepaddle-gpu==2.6.1 cudatoolkit=11.7 -c conda-forge

pip  install  --dry-run paddleocr

conda install  -c conda-forge Cython PyYAML beautifulsoup4 charset-normalizer colorama contourpy cycler fire fonttools imageio  kiwisolver lazy_loader lmdb  lxml matplotlib networkx packaging  pyclipper pyparsing python-dateutil python-docx  rapidfuzz requests  scikit-image scipy shapely six soupsieve termcolor  tifffile  tqdm urllib3

conda  install  -c conda-forge --dry-run  imgaug

下面3个程序，无法用conda安装

pip install --dry-run  --no-deps opencv-python

pip install --dry-run  --no-deps opencv-contrib-python 

pip install --dry-run  --no-deps imgaug

#paddleocr 会将numpy降级到2.0以下

pip install --dry-run  --no-deps paddleocr

numpy不降级，paddleocr不能用

paddleocr --image_dir .\img\zsbf.jpg

AttributeError: `np.sctypes` was removed in the NumPy 2.0 release. Access dtypes explicitly instead.. Did you mean: 'dtypes'?

find命令

root@debian:/# find /   -path  /mnt/disk -prune  -type f  -name   2GSRM4Z7.zip

root@debian:/# find /   -path ./mnt/disk -prune  -type f  -name   2GSRM4Z7.zip

root@debian:/# find /                                         -type f   -name   2GSRM4Z7.zip

为什么只有第3个命令能找到文件？

how-to-use-prune-option-of-find-in-sh

find / -path /mnt/disk  -prune -o -name '2GSRM4Z7.zip' -print

上面的命令，能找到文件。

chrome socks5 proxy from cmd

 https://www.chromium.org/developers/design-documents/network-stack/socks-proxy/

To configure chrome to proxy traffic through the SOCKS v5 proxy server myproxy:8080, launch chrome with these two command-line flags:

--proxy-server="socks5://myproxy:8080"

--host-resolver-rules="MAP * ~NOTFOUND , EXCLUDE myproxy"

Explanation

The --proxy-server="socks5://myproxy:8080" flag tells Chrome to send all http:// and https:// URL requests through the SOCKS proxy server "myproxy:8080", using version 5 of the SOCKS protocol. The hostname for these URLs will be resolved by the proxy server, and not locally by Chrome.

NOTE: proxying of ftp:// URLs through a SOCKS proxy is not yet implemented.

The --proxy-server flag applies to URL loads only. There are other components of Chrome which may issue DNS resolves directly and hence bypass this proxy server. The most notable such component is the "DNS prefetcher".Hence if DNS prefetching is not disabled in Chrome then you will still see local DNS requests being issued by Chrome despite having specified a SOCKS v5 proxy server.

Disabling DNS prefetching would solve this problem, however it is a fragile solution since once needs to be aware of all the areas in Chrome which issue raw DNS requests. To address this, the next flag, --host-resolver-rules="MAP * ~NOTFOUND , EXCLUDE myproxy", is a catch-all to prevent Chrome from sending any DNS requests over the network. It says that all DNS resolves are to be simply mapped to the (invalid) address 0.0.0.0. The "EXCLUDE" clause make an exception for "myproxy", because otherwise Chrome would be unable to resolve the address of the SOCKS proxy server itself, and all requests would necessarily fail with PROXY_CONNECTION_FAILED.
