Overview# I built a Gradio App using NDL Kotenseki OCR-Lite .
You can try it at the following URL.
https://huggingface.co/spaces/nakamura196/ndlkotenocr-lite
“NDL Kotenseki OCR-Lite” provides a desktop application, so an execution environment is available without the need for a web app like Gradio.
Therefore, the intended use cases for this web app include usage from smartphones or tablets, and integration via web API.
Development Notes and Bug Fixes# Using Submodules# The original ndlkotenocr-lite was introduced as a submodule.
[ s p u u a r b t l m h o = d = u h l n t e d t l p " k s n o : d t / l e / k n g o o i t c t e r h n - u o l b c i . r t c - e o l m i / t n e d " l ] - l a b / n d l k o t e n o c r - l i t e . g i t
The following is executed during the build.
# # g g ! i i / I t t b n i i s s n t u u / i b b b a m m a l o o s i d d h z u u e l l e e a n u u d p p d d u a a p t t d e e a t e - - i r s n e u i m b t o m t o e d - u r l e e c u r s i v e This should allow the latest files from the original ndlkotenocr-lite to be used during the build.
(There may be some misunderstandings on my part.)
Using Dockerfile# For using the submodule, a Dockerfile-based build approach was adopted.
By setting the sdk to docker, the build is performed based on the Dockerfile.

V a l u e E r r o r : C o u l d n o t f e t c h a p i i n f o f o r h t t p s : / / n a k a m u r a 1 9 6 - n d l k o t e n o c r - l i t e . h f . s p a c e / : { " d e t a i l " : " N o t F o u n d " }
By using version 4.44.1, this error was resolved.

Summary# I am grateful that “NDL Kotenseki OCR-Lite” was released as OSS.
I may be unfamiliar with Docker-based development and there may be inaccuracies, but I hope this serves as a helpful reference.
