Tried output redirection to store training log yet produced an empty file? Here's a solution.

[hxu296]

This issue happened to me both for PoseFormer and VideoPose3D - I tried to use output redirection (&>) to save the training loss but received an empty file. This is due to Python's buffering. To solve the problem, use the python -u flag to ask for unbuffered output.

Example:
python -u run_poseformer.py -k cpn_ft_h36m_dbb -f 9 -lr 0.00004 -lrd 0.99 &> 9f_cpn.log
