Trying to run on Mac m1

[Pawandeep-prog]

My Mac configs:
os: Mac OS 13.4 (22F66)
cpu: Mac m1
ram: 8GB

after running through
sh scripts/gui.sh

I am getting segment fault:
scripts/gui.sh: line 2: 77912 Segmentation fault: 11 python visualizer_drag.py checkpoints/stylegan2_lions_512_pytorch.pkl

need any more information would be happy to share.

[Pawandeep-prog]

after further tracking the code,

found that the fault is due to this line

self.set_window_size(window_width, window_height)

from gui_utils/glfw_window.py in the init() function.

[Pawandeep-prog]

okay resolved segmentation fault

it was due to
self.monitor_height and self.monitor_width variables
in the same file def set_window_size(self, width, height): this function

I removed them and hard coded 1920 and 1080 instead.

any help would be appreciated :)

@Pawandeep-prog I fixed the issue by following this suggestion.

[Pawandeep-prog]

I think it require cuda to run as I see in stylegan3 repo, and I am running Mac m1 maybe that is the issue. :(

MacOS
M1

scripts/gui.sh: line 1: python: command not found
Line 1 😭 ，How to resolve it？Help me pls

[aBner6667]

I can open the generated web address, and the interactive content is displayed correctly. However, once I click to manipulate the image, it shows an error： ”Expecting value: line 1 column 1 (char 0)“,
I am a computer newbie, please help me.

MacOS M1

@albusdemens when you say fixed, do you mean the project was running?

I track my issue, I found the problem is caused by : _, _, _width, height = glfw.get_monitor_workarea(glfw.get_primary_monitor()), in glfw_window.py, line 82.
My macbook pro is MacOS Monterey 2021, M1 pro chip.
It return a null pointer while it tried to query the monitor size, but fail
It seems like the glfw library didn't have good support in arm chip. Maybe using Metal could resolve it?

[Pawandeep-prog]

I also had problem over there, didn't found any solution so I hard coded these values. :(

[siyun-liang]

I try:

        glfw.window_hint(glfw.CONTEXT_VERSION_MAJOR, 3)
        glfw.window_hint(glfw.CONTEXT_VERSION_MINOR, 3)
        glfw.window_hint(glfw.OPENGL_FORWARD_COMPAT, glfw.TRUE)
        glfw.window_hint(glfw.OPENGL_PROFILE, glfw.OPENGL_CORE_PROFILE)

I want to set the openGL context to 3.3, while:
version = gl.glGetString(gl.GL_VERSION)
print("OpenGL Version:", version)
prints OpenGL Version: b'4.1 Metal - 83.1'. (without the change it prints 2.1 Metal)

With this change:
self._imgui_renderer = _GlfwRenderer(self._glfw_window)
in line 40, imgui_window.py throws no exception.

But further exception was thrown: gui_utils/glfw_window.py", line 193, in begin_frame

OpenGL.error.GLError: GLError(
	err = 1282,
	description = b'invalid operation',
	baseOperation = glMatrixMode,
	cArguments = (GL_PROJECTION,)
)

I have spent a fair amount of time debugging this issue and concluded that the codebase cannot run on macOS without a significant refactoring of the OpenGL code.

The OpenGL code in visualizer.py and gl_utils.py uses APIs that were released after OpenGL 2.1 and fixed function pipeline API (for example glMatrixMode). macOS has a known issue with that, specifically it cannot mix legacy functions with newer 3.2+ functions. This is mentioned in the official OpenGL wiki:

Platform Issue (MacOSX): When MacOSX 10.7 introduced support for OpenGL beyond 2.1, they also introduced the core/compatibility dichotomy. However, they did not introduce support for the compatibility profile itself. Instead, MacOSX gives you a choice: core profile for versions 3.2 or higher, or just version 2.1. There is no way to get access to features after 2.1 and still access the Fixed Function Pipeline.

See https://www.khronos.org/opengl/wiki/OpenGL_Context#OpenGL_3.2_and_Profiles

The only path forward to make this work on macOS is to migrate code which uses the fixed function pipeline to use shader-based programming instead.
