禁用pve-ha-crm和pve-ha-lrm服务：

systemctl stop pve-ha-lrm.service pve-ha-crm.service
systemctl disable pve-ha-lrm.service pve-ha-crm.service

修改/etc/default/rrdcached：

#添加
WRITE_TIMEOUT=3600
FLUSH_TIMEOUT=7200
#注释此行
##JOURNAL_PATH=/var/lib/rrdcached/journal/

修改/etc/init.d/rrdcached变量RRDCACHED_OPTIONS处添加：

${FLUSH_TIMEOUT:+-f ${FLUSH_TIMEOUT}} \

重启rrdcached：

systemctl daemon-reload 
systemctl restart rrdcached.service

安装paddleocr：

apt install python3-pip libgl1
pip3 install paddlepaddle paddleocr

paddleocr cli使用：

paddleocr --image_dir test.jpg --lang ch --show_log False --det_db_unclip_ratio 2.5

python使用：

from paddleocr import PaddleOCR

ocr = PaddleOCR(use_angle_cls=True, lang="ch", det_db_score_mode="slow", show_log=False, use_gpu=False, det_db_unclip_ratio=2.5) 

img_path = 'test.jpg'
result = ocr.ocr(img_path, cls=True)
txts = [line[1][0] for line in result]
print(*txts)

如遇到错：

AttributeError: partially initialized module 'cv2' has no attribute 'gapi_wip_gst_GStreamerPipeline' (most likely due to a circular import)

安装指定版本opencv-python：

pip uninstall opencv-python
pip install opencv-python==4.5.5.64
