@Sfonxu (as we talked about it today), the key issue here is that without the change the code would not work, but the change is in a conditional branch that...

after logging in to the CI worker, it seems that no mp4 file is produced :( ``` runner@fv-az1280-241:~/work/PySDM/PySDM$ ls /tmp/pytest-of-runner/pytest-0/test_run_notebooks__home_runne1/output/ last_animation_frame.pdf sd_attributes_num0000000348.vtu sd_attributes_num0000000720.vtu sd_products.pvd sd_products_num0000000360.vts sd_products_num0000000732.vts sd_attributes.pvd sd_attributes_num0000000360.vtu sd_attributes_num0000000732.vtu sd_products_num0000000000.vts...
