Troubleshooting Jupyter Notebook: Stuck on In [*]
A Jupyter Notebook stuck on "In []" indicates the kernel is busy executing code but hasn't completed. Common causes include infinite loops, resource-intensive computations (memory or CPU), or a blocked input request. First, try interrupting the kernel by pressing the "Interrupt" button in the toolbar (or Kernel -- Interrupt). If that fails, restart the kernel (Kernel -- Restart). Save your notebook before restarting, as you may lose unsaved changes. If the problem persists after restarting, examine your code for potential infinite loops or memory leaks. Reduce the size of data being processed or optimize computationally intensive sections. Check for any external dependencies or blocking input requests that might be hindering execution. As a last resort, restart the entire Jupyter Notebook server.
