ollama - 💡(How to fix) Fix Crash on Windows: Exception 0xc0000005 in MLX during startup [1 comments, 1 participants]

Ollama crashes immediately on startup (or when running any command like ollama --version) with an access violation error (0xc0000005). The crash appears to originate from the MLX image generation module. Immediate crash with the following error: `Exception 0xc0000005 0x8 0x7fff05cecb12 0x7fff05cecb12

Fix Plan

The fix involves updating the MLX image generation module to handle compatibility issues with Windows.

• Update the go.mod file to use the latest version of the MLX library.
• Modify the mlx.go file to include error checking for the mlx_random_key function.
• Use the following example code to handle the error:

// mlx.go
package mlx

/*
#include <mlx.h>
*/
import "C"
import "unsafe"

func RandomKey() (key []byte, err error) {
    // Check if the MLX library is initialized
    if C.mlx_init() != 0 {
        return nil, fmt.Errorf("failed to initialize MLX library")
    }
    // Call the mlx_random_key function
    cKey := C.mlx_random_key()
    if cKey == nil {
        return nil, fmt.Errorf("failed to generate random key")
    }
    // Convert the C string to a Go byte slice
    key = C.GoBytes(unsafe.Pointer(cKey), C.mlx_key_len())
    return key, nil
}

• Rebuild the Ollama application with the updated MLX library.

Verification

To verify the fix, run the Ollama application with the --version flag. If the application starts without crashing, the fix is successful.

Extra Tips

• Ensure that the MLX library is compatible with the Windows operating system.
• Check for any other dependencies that may be causing compatibility issues.
• Test the application on different environments to ensure that the fix is not specific to one setup.
