bpycv.render_data error

[liuyanqi]

There is an error with the random file name saved in /tmp/. Seems like the it was not able to generate the random filename.
I'm using blender 2.93 and python 3.9

Render image using: BLENDER_EEVEE
Saved: '/tmp/.png'
 Time: 00:00.18 (Saving: 00:00.00)

Looks like withattr(render, "filepath", png_path) in render_image dose not work, and image are saved to '/tmp/.png'

We have test bpycv on blender2.90, blender3.0 and blender3.1
You can try another blender version first.
