NumPy array metadata (shape, dtype, ndim)

Type: Feature Request

Hello VS Code team,

Feature request: please add an option to show NumPy array metadata (shape, dtype, ndim) directly in the Variables/Locals view when debugging Python. Current workarounds (Data Viewer, Watch, Debug Console) are helpful but a compact shape/dtype column would greatly speed up debugging numeric code.

Use case:

• Quickly inspect array shapes/dtypes (e.g., frame.shape, frame.dtype) while paused at breakpoints without opening the Data Viewer or adding watches.
• Helpful for image-processing / ML workflows where many arrays are inspected frequently.

Suggested design:

• Add optional compact badges or columns in Variables: name | type | shape | dtype | value-preview.
• Or provide a toggle Python: Show Array Shape/DType in Variables.

Repro steps:

1. Open a Python file using NumPy arrays.
2. Start debugger and pause on a line where arrays exist.
3. Observe Variables view — shape/dtype not visible by default.

Environment:

• VS Code version: 1.109.4
• Python extension: 2026.2.0
• OS: linux

Thanks for considering.

Regards,

Modes:

Inizia individuando il punto di ingresso per il rendering di Variables/Locals nell’estensione di debug TypeScript e verificando come vengono rappresentati i valori Python in pausa. Determina dove potrebbero essere esposti shape, dtype e ndim di NumPy e come dovrebbe comportarsi una visualizzazione opzionale; il lavoro è completato quando i metadati richiesti sono visibili mentre l’esecuzione è in pausa senza richiedere Data Viewer o watches.
