worker.recognize memory leak #678

I investigated the cause of the memory leak and confirmed that leak is caused by the setImage function. Repeatedly running image recognition without I was unable to figure out how to adapt the existing code (which creates the image object on the Javascript side) to not have this issue. However, writing the image to the filesystem and then reading it to a |

@Balearica . Thank you for the update. Could you please let me know if there is any way I can update the code in nodejs server or do I have to wait until the next version is published? Thank you |

@engageaffli The upcoming changes in version 4 (which includes this fix) are explained in #662. You should review as there are additional changes in that version. To use version 4 while in development you would just need to (1) replace the contents of your current Tesseract.js folder with the dev/v4 branch of this repo and (2) replace the contents of your current Tesseract.js-core folder with the dev/v4 branch of the Tesseract.js-core repo. |
See #662 for explanation of Tesseract.js Version 4 changes. List below is auto-generated from commits. * Added image preprocessing functions (rotate + save images) * Updated createWorker to be async * Reworked createWorker to be async and throw errors per #654 * Reworked createWorker to be async and throw errors per #654 * Edited detect to return null when detection fails rather than throwing error per #526 * Updated types per #606 and #580 (#663) (#664) * Removed unused files * Added savePDF option to recognize per #488; cleaned up code for linter * Updated download-pdf example for node to use new savePDF option * Added OutputFormats option/interface for setting output * Allowed for Tesseract parameters to be set through recognition options per #665 * Updated docs * Edited loadLanguage to no longer overwrite cache with data from cache per #666 * Added interface for setting 'init only' options per #613 * Wrapped caching in try block per #609 * Fixed unit tests * Updated setImage to resolve memory leak per #678 * Added debug output option per #681 * Fixed bug with saving images per #588 * Updated examples * Updated readme and Tesseract.js-core version

Closing as this should be resolved in Version 4. |
A memory leak exists in
worker.recognize. When the same worker is used for recognizing many files, memory slowly increases, and eventually the program crashes. To replicate this issue, run the benchmark.js example, except withi < 10changed toi < 100. On my system this fails on the 84th recognition job.The text was updated successfully, but these errors were encountered:
