生成 Tesseract 训练数据失败

我在 Windows 10 上使用 Tesseract v5.0.1.20220118，训练只有字母“P”和“Q”的字体。

当我执行到此步骤时，

mftraining -F font_properties.txt -U unicharset -O normal.unicharset pq.normal.exp0.tr

未生成 pffmtable 文件。

当我运行代码 cntraining pq.normal.exp0.tr

它告诉我

Reading pq.normal.exp0.tr ...
Clustering ...
N == sizeof(Cluster->Mean):Error:Assert failed:in file ../../../src/classify/cluster.cpp, line 2526

为什么会出错？我该如何修复它？

我只生成了 inttemp 和 shapetable，但教程说会有四个文件，包括 shapetable、inttemp、 pffmtable 和 normproto，我想知道可能是因为字体只有字母“P”和“Q”，但我不知道如何解决。

原文

I'm using Tesseract v5.0.1.20220118 on Windows 10, training a font only have letter "P" and "Q".

When I get to the step

mftraining -F font_properties.txt -U unicharset -O normal.unicharset pq.normal.exp0.tr

The pffmtable file is not generated.

And when I run code cntraining pq.normal.exp0.tr

It shows me

Reading pq.normal.exp0.tr ...
Clustering ...
N == sizeof(Cluster->Mean):Error:Assert failed:in file ../../../src/classify/cluster.cpp, line 2526

Why it goes wrong? How can I fix it?

I only have inttemp and shapetable generated, but the tutorial says there will be four files include shapetable, inttemp, pffmtable and normproto, I wonder that maybe is beacuse of the font only have letter "P" and "Q", but I have no idea how to solve it.
