I am following
this tutorial but when running this command (step 5):
```
mftraining -F font_properties -U unicharset -O eng.unicharset
eng.dharma-gothic-e.exp0.tr```
I get this error:
```
Warning: No shape table file present: shapetable
Reading
eng.dharma-gothic-e.exp0.tr ...
Font id = -1/0, class id = 1/64 on sample 0
font_id >= 0 && font_id < font_id_map_.SparseSize():Error:Assert failed:in file ..\..\classify\trainingsampleset.cpp, line 622
```
I will attach a folder which contains all the files tesseract made
