Increased profiling accuracy, Python 3.11 support

Changes in this release:

• increased accuracy of time attribution to specific lines for CPU & GPU profiling (also reduces memory consumption)
• increased accuracy of memory attribution to specific liens
• added per-process GPU accounting for NVIDIA, which can dramatically increase accuracy when profiling on shared GPUs
• added support for Python 3.11
• documented the command-line option to force Scalene to ignore options after that point (---)

Full Changelog: v1.5.8...v1.5.9.1

Minor UI update: memory activity now shown as pies instead of numbers

What's Changed

UI improvements:

• Memory activity now shown as pies instead of numbers

Compatibility:

• Working towards conda builds.

Full Changelog: v1.5.6...v1.5.7

Bug fixes for memory attribution and multiprocessing

What's Changed

Improved functionality and accuracy:

• Fixed Python memory attribution for large requests.
• Fixed an issue with the multiprocessing library.

UI improvements:

• Fixed reporting of the Python fraction of memory allocated.

Compatibility:

• Removed nvidia-ml-py dependency, which was causing a reported issue with Dask (#378).

Full Changelog: v1.5.5...v1.5.6

Bug fixes, improved CPU and memory accounting

What's Changed

Improved functionality and accuracy:

• Fixed occasional segfaults caused by unaligned memory allocations.
• Corrected an issue with attribution of CPU time with threads.
• Leak detection enabled by default.

UI improvements:

• Hovering over memory timelines now shows amount of memory consumed, and when.
• Memory timelines are compressed, reducing the size of profiles and reducing the memory consumption of the UI.
• Suspected leaks are now highlighted.

Compatibility:

• Moved to Python 3.8.

Full Changelog: v1.5.4...v1.5.5

Improved UI, especially for GPU usage; accuracy and compatibility improvements

What's Changed

Improved functionality and accuracy:

• Fixed memcpy attribution (now on specific lines, just like allocations).
• GPU profiling now enabled on Apple systems

UI improvements:

• Memory timelines are now zoomable.
• Fatter bars, zoomable timelines, fixed sorting for code line separators
• Added explanations when hovering over column headers.
• Omit function summaries if no functions.
• Added GPU memory profiling.
• Report peak instead of average GPU memory.
• GPU utilization now pies.

Compatibility:

• Fixed Windows support
• Added support for profiling programs that use signals

Full Changelog: v1.5.3...v1.5.4

Maintenance release: fixes virtualized GPU issue, Windows loading, output issue

What's Changed

• Adds exception handling to workaround a virtualized GPU issue (#323).
• Added average memory consumption calculation to function summaries.
• Fixes a missing argument issue in output (#344)
• Fixes an issue with Jupyter notebooks when they don't have access to a web browser.

Full Changelog: v1.5.2...v1.5.3

Jupyter support for new GUI; auto-exit of server

What's Changed

• Scalene's web-based GUI is now integrated into Jupyter notebooks
• When using --cpu-only or profiling in Jupyter, columns for memory profiling (which would all be empty) are now hidden
• The local webserver now exits after 5 seconds.

Full Changelog: v1.5.1...v1.5.2

Local web-based GUI

What's Changed

• Scalene now launches its web-based GUI locally by default. After profiling, It opens a browser tab to a local webserver and automatically brings up the most recent profile. (The old behavior is still available by using --cli on the command line.)
