Overview

cudaErrorStreamCaptureInvalidated indicates graph capture was invalidated by an error during recording.

Error Messages

CUDA error: stream capture invalidated
cudaErrorStreamCaptureInvalidated

Common Causes

• •Error during capture
• •Unsupported operation attempted
• •Capture mode violation

Solutions

cudaStreamEndCapture(stream, &graph);
cudaGraphDestroy(graph);
// Fix issue and retry capture

cudaError_t err;
err = someOperation();
if (err != cudaSuccess) {
    // Capture invalidated, must restart
}

Prevention Tips

• ✓Check errors during capture
• ✓Use try-catch pattern for capture
• ✓Test capture path thoroughly

Code Examples

Before (Problematic)

Using invalidated capture.

cudaStreamBeginCapture(stream);
// Some error occurs...
cudaStreamEndCapture(stream, &graph);  // graph invalid

After (Fixed)

Handle invalidation.

cudaStreamBeginCapture(stream);
if (doOperations() != cudaSuccess) {
    cudaStreamEndCapture(stream, &graph);
    cudaGraphDestroy(graph);
    return retry();
}
