Tesseract 3.0.5 - Text2Image

[john brown]

Hello. I'm running Text2Image to automate some training data but I keep getting the following error:

Unable to open '/tmp/fonts.conf' for writing

Fontconfig error: Cannot load default config file

FcInitiReinitialize failed!!

Failed to read file: training_text.txt

Any ideas what is causing this? This is the following command I'm running

text2image --text=training_text.txt --outputbase=eng --fonts_dir=C:\\Windows\\Fonts --find_fonts --min_coverage=1.0 --render_per_font=false

Thanks

That's my issue, I don't understand what /tmp is. I'm on Windows 10 (Might be the first issue!)

/tmp (on linux) is the (global) folder for storing temporary files, where usualy every user/service/tool has access. something like %temp% on windows. Maybe you can try to create c:\tmp if it helps...

This is absolutely bizarre. I'm able to run and generate a  .box and .tif file when I run my rectified command in the command prompt. Now, I tried the exact same command using C# and it's now saving "Unable to read trainng_text.txt". 

[john brown]

Okay. I've successfully finished the training process for 3.0.5 using the legacy engine. Now, I'm pretty sure 3.0.5 also supports the LSTM engine too? I can't seem to find anything on the training tesseract wiki page for using LSTM...

[ShreeDevi Kumar]

3.0.x branch is for legacy engine.

LSTM support is only in master branch, for 4.0x

Currently master branch also supports legacy engine, though it may go away later.

See wiki pages regarding 4.0. There is a detailed page on training.
