FileNotFoundError python continuum_snake.py

[dvogureckiy99]

Describe the bug
I tried to run continuum_snake_render.py example

To Reproduce
First script goes well.

python continuum_snake.py        
Total steps 220199
100%|█████████████████████████████████████████████████████████████████████| 220199/220199 [01:26<00:00, 2549.20it/s]
Final time of simulation is :  11.009999999978538
Datafile Created

But next bad:

python continuum_snake_render.py

The above exception was the direct cause of the following exception:

    for message in p.imap_unordered(func, batch):

hi @dvogureckiy99 the ContinuumSnakeCase has no file called continuum_snake_render.py. Hence you get the FileNotFoundError. Please re check the names of existing scripts before running them. @armantekinalp feel free to close this issue.
