e161501df6 Optimize performance by using inline MatrixDotVectorInternal 
This improves performace for the "best" models because it
avoids function calls.

The compiler also knows the passed values for the parameters
add_bias_fwd and skip_bias_back.

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.

Fix wrong results from function streamtofloat
 2018-11-18 08:11:55 +01:00
Stefan Weil
a93426c9ff Fix wrong results from function streamtofloat 
The local variable k should be 10 ^ (number of digits after comma),
but will overflow when there are more than 9 digits after the comma
because an int value cannot store 10000000000.

This results in wrong double values read from .tr files for example
(or in a runtime exception if Tesseract was compiled with -ftrapv).

Using uint64_t does not fix the general problem but allows more digits
which should be sufficient for the data read by Tesseract.

The commit 10f2c45c00 unified the usage of mktemp, but with a
incorrect bash syntax and unnecessary definition of LANG_CODE
and TIMESTAMP. This patch fixes the above problems.
