ValueError: current limit exceeds maximum limit

[curious-itauditor]

Does anyone experienced and fixed below value error:

Deep-Live-Cam/run.py", line 99, in
core.run()
File "/x/Deep-Live-Cam/modules/core.py", line 347, in run
limit_resources()
File "/xDeep-Live-Cam/modules/core.py", line 188, in limit_resources
resource.setrlimit(resource.RLIMIT_DATA, (memory, memory))
ValueError: current limit exceeds maximum limit

I'm using MacBook Air M2 8gb ram

I tried running this code but Terminal and Python crashes: python run.py --execution-provider coreml --max-memory 0

This is a known macOS-specific failure in limit_resources(), not a CoreML model error.

The current code applies this to every non-Windows system:

resource.setrlimit(resource.RLIMIT_DATA, (memory, memory))

Some macOS/Python combinations reject that RLIMIT_DATA value with EINVAL; CPython exposes it as the misleading ValueError: current limit exceeds maximum limit. The same problem is tracked in #1848, with fixes proposed in #1849 and #1860.

The minimal local fix is to apply RLIMIT_DATA only on Linux:

if platform.system().lower() == "windows":
    import ctypes
    kernel32 = ctypes.windll.kernel32
    kernel32.SetProcessWorkingSetSize(
        -1, ctypes.c_size_t(memory), ctypes.c_size_t(memory)
    )
elif platform.system().lower() == "linux":
    import resource
    resource.setrlimit(resource.RLIMIT_DATA, (memory, memory))

In other words, skip that call on Darwin/macOS. This is also the approach in #1849.

--max-memory 0 should bypass setrlimit because the code is guarded by if modules.globals.max_memory:. If Python or Terminal is then killed without this traceback, that is a separate macOS memory-pressure/OOM event rather than the original ValueError; an 8 GB machine may need a smaller target/video and fewer processors. First apply the Darwin guard and run normally with CoreML so you can distinguish the two failures.
