Install & Compatibility

Code

Verified usage

Load the extension in IPython or Jupyter notebook. It will start timing all cells.

%load_ext autotime # After loading, every cell shows execution time automatically

Debug

Known issues

gotchaRunning '%load_ext autotime' in a terminal that doesn't support IPython will fail with ImportError or ModuleNotFoundError.

fix

Ensure you are using IPython, Jupyter notebook, or JupyterLab. Do not run in plain Python interpreter.

affects: all

gotchaTiming includes the time to import modules and run setup inside the cell, not just the main computation.

fix

If you need to exclude import overhead, move imports outside the timed cell.

affects: all

gotchaautotime uses time.perf_counter or monotonic clock; wall time may vary due to system load.

fix

For reproducible benchmarks, use %timeit or timeit module instead.

affects: all

deprecatedVersions before 0.3.0 did not show the 'started' timestamp. If you rely on old output format, format changed.

fix

Update to 0.3.0+ or parse the new output format.

affects: < 0.3.0

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'autotime'

Trying to import autotime as a Python module directly, or running outside IPython.

fix

Run 'pip install ipython-autotime' and then use '%load_ext autotime' inside IPython/Jupyter.

UsageError: Line magic function `%autotime` not found.

Forgot to load the extension first, or extension not installed correctly.

fix

First run '%load_ext autotime', then '%autotime' can be used (though usually you just load it).

TypeError: enable_autotime() got an unexpected keyword argument 'started'

Using an older version of ipython-autotime that doesn't support the 'started' argument.

fix

Update to the latest version: 'pip install --upgrade ipython-autotime'
