Blender 2.8+ - Baking textures on headless machine (batch baking)?

Question

I'm a noob when it comes to scripting so I came across this solution: Baking textures on headless machine (batch baking) But unfortunately, I can't make it work for 2.8+:

bake_all.py

import bpy
import os
scene = bpy.context.scene
for obj in scene.objects:
    obj.select = False
for obj in scene.objects:
    if obj.type != 'MESH':
        continue
scene.objects.active = obj
obj.select = True

bpy.ops.object.bake(type='COMBINED')
obj.select = False


save all baked images
for image in bpy.data.images:
    if image.is_dirty:
        # foo.png -> foo_bake.png
        filepath, filepath_ext = os.path.splitext(image.filepath_raw)
        image.filepath_raw = filepath + "_bake" + filepath_ext
        image.save()

Q: How to execute the script in latest versions?

Updated the code based on the comments and it still doesn't work:

import bpy
import os
scene = bpy.context.scene
scene.render.engine = 'CYCLES'
for obj in scene.objects:
    obj.select_set(False)
for obj in scene.objects:
    if obj.type != 'MESH':
        continue
bpy.context.view_layer.objects.active = obj
obj.select_set(True)

bpy.ops.object.bake(type='COMBINED')
obj.select_set(False)


save all baked images
for image in bpy.data.images:
    if image.is_dirty:
        # foo.png -> foo_bake.png
        filepath, filepath_ext = os.path.splitext(image.filepath_raw)
        image.filepath_raw = filepath + "_bake" + filepath_ext
        image.save()
bpy.ops.image.save

This is not working on my remote PC, it works fine on my local PC but not on my remote farm. What am I doing wrong?

this is not doing anything

# save all baked images
for image in bpy.data.images:
    if image.is_dirty:
        # foo.png -> foo_bake.png
        filepath, filepath_ext = os.path.splitext(image.filepath_raw)
        image.filepath_raw = filepath + "_bake" + filepath_ext
        image.save()

in terminal it says

Info: Baking map saved to internal image, save it externally or pack it

only the bake file is created that is not usable... do I need to add the filepath?

I tried to add save file and download blender file to open it locally but no baked textures within...

I get line 6, in <module> obj.select = False AttributeError: 'Object' object has no attribute 'select' — sephiroth85, Dec 15 '20 at 10:43
Okay, my bad it did have some outdated lines. Please check the answer you provided, I updated the code for 2.8+. basically obj.select became a method obj.select_set(state) and now with view layers you have to set the active object per view layer. scene.objects.active = obj becomes bpy.context.view_layer.objects.active = obj — Gorgious, Dec 15 '20 at 10:44
line 201, in call ret = op_call(self.idname_py(), None, kw) RuntimeError: Error: No valid selected objects — sephiroth85, Dec 15 '20 at 11:54
@Gorgious after bake it seems that blender doesnt save the files? — sephiroth85, Dec 15 '20 at 14:19
Have tested the script and it seems to work properly. I'd suggest share your blend preferably using https://blend-exchange.giantcowfilms.com/ and add the blend to your question to figure out your issue... — brockmann, Dec 15 '20 at 14:52
done, what I want to do it, is to run baking on my remote render farm that I have — sephiroth85, Dec 15 '20 at 20:02
as mentioned this is not working on my remote PC, it works fine on my local pc but not on my remote farm — sephiroth85, Dec 21 '20 at 23:54
