If you found problems running the working example (v0.1.25) because of https://github.com/cocoa-xu/evision/issues/179, please, download the charset before testing: 

wget https://raw.githubusercontent.com/opencv/opencv_zoo/933a4171e3dfa2f67b4078602c76f91ac6a5299a/models/text_recognition_crnn/charset_3944_CN.txt -O ~/.cache/text_recognition_CRNN_CN_2021nov_charset_3944_CN.txt

Hey, thank you for the time and effort you spend on this amazing library! 💜

Thank you for reporting this issue! I plan to write some tests for these smart cells in the next version so that I can notice if anything is broken before shipping it out. ;)
