Not working (Moodle 3.7.2, Python 2.7, moodlemlbackend 1.0.1 & requirements) #15

I have

Earlier I had one problem with tensorflow v1.14.0, which crashed with my CPU,

Nov 4 17:12:32 moodle37 kernel: [9773297.574293] traps: python2.7[4570] trap invalid opcode ip:7fb9b74bca59 sp:7ffdb7605e10 error:0 in libtensorflow_framework.so.1[7fb9b6d97000+18f8000]

I also got:

python -c 'import tensorflow'
Illegal instruction

So I had to build from source with following build options: -march=nehalem -msse4.1 -msse4.2 -mpclmul -mpopcnt -maes -mno-avx -mno-avx2

Now python -c 'import tensorflow' results nothing, so it is imported successfully.

After fixing tensorflow v1.14.0, still no result in Moodle v3.7.2 when I go to Dashboard/Site administration/Analytics/Analytics models/Students at risk of dropping out/Get predictions: Result: There is no new data that can be used for training Dashboard/Site administration/Analytics/Analytics models/Students at risk of dropping out/Evaluate model: Result: No results returned from the predictions processor. Check the output directory contents for more information.

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

Any idea how can I make it work? How could I debug the problem?
