Should update version requirement for scipy in 'examples\\distillation\\requirements.txt'?
There are inconsistent  version requirements for scipy in 'examples\\distillation\\requirements.txt' and 'examples\\movement-pruning\\requirements.txt'. Fixed version **1.3.1** in 'examples\\distillation\\requirements.txt' is not in the version range in **'>=1.4.1'** in  'examples\\movement-pruning\\requirements.txt'.

**Solution**
I am wondering if it is necessary to update the version requirement in 'examples\\distillation\\requirements.txt' to be consistent. Fixed version can often cause conflict. 
@VictorSanh what do you think?
