25fa392887 Added an additional optional --tmp_dir parameter to specify the temporary directory in which tesstrain.py creates the training temporary files. The main reason is due to the slow R/W on HDD, if anyone wants to speed up this process can use as tmp_dir a directory on an SSDrive 2019-03-04 13:26:53 +00:00

ecf73f5bc7 training: Don't terminate after processing 8 fonts or 8 images
tesstrain_utils.sh sets the shell flag -e, so it exits immediately
if a command exits with a non-zero status.

The following command returns a non-zero status as soon as counter is a
multiple of par_factor (par_factor=8, that means as soon as 8 fonts or
images are processed):

    let rem=counter%par_factor

The new code fixes this undesired exit.

e4b862d588 pango_font_info: Fix runtime error messages from Pango
pango_coverage_get and pango_coverage_unref should not be called
with coverage == nullptr.

pango_font_get_coverage should not be called with font == nullptr.

Otherwise Pango prints runtime error messages:

    (process:12657): Pango-CRITICAL **: pango_coverage_get: assertion 'coverage != NULL' failed
    (process:12657): Pango-CRITICAL **: pango_coverage_unref: assertion 'coverage != NULL' failed
    (process:12657): Pango-CRITICAL **: pango_font_get_coverage: assertion 'font != NULL' failed
    (process:12657): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

Typically those errors occur if a required font is not installed,
so this can be a quite common error.

Fix also a potential resource leak in PangoFontInfo::CoversUTF8Text.

d9ae7ecc49 Pythonize tesstrain.sh -> tesstrain.py
This is a lightweight, semi-Pythonic conversion of tesstrain.sh that currently
supports only LSTM and not the Tesseract 3 training mode.

I attempted to keep source changes minimal so it would be easy to compare
bash to Python in code review and confirm equivalence.

Python 3.6+ is required.  Ubuntu 18.04 ships Python 3.6 and it is a mandatory
package (the package manager is also written in Python), so it is available
in the baseline Tesseract 4.0 system.

There are minor output and behavioral changes, and advantages.  Python's loggingis used.  Temporary files are only deleted on success, so they can be inspected
if training files.  Console output is more terse and the log file is more
verbose.  And there are progress bars!  (The python3-tqdm package is required.)
Where tesstrain.sh would sometimes fail without explanation and return an error
code of 1, it is much easier to find the point of failure in this version.
That was also the main motivation for this work.

Argument checking is also more comprehensive.
