Copy a W&B saved-view template across projects

| """Copy a W&B saved-view template from one project's workspace to another. | | | Reads the source saved view via its URL (the ?nw=<id> query string identifies | | | the saved view) and reconstructs an identical Workspace in the destination | | | project — preserving sections/panels, workspace settings (smoothing, x-axis, | | | outliers, etc.), and runset settings (filters, grouping, ordering, pinned | | | columns, per-run colors/disabled state). | | | Setup: | | | pip install wandb wandb-workspaces | | | export WANDB_API_KEY=<your key> # or have it in ~/.netrc via wandb login | | | Usage: | | | python copy_savedview.py \ | |

| --source-url "https://wandb.ai/ENTITY/SRC_PROJECT?nw=abcd1234" \ | |
| --dest-entity ENTITY \ | |
| --dest-project DST_PROJECT \ | |
| --new-name "Copied template" | |

| Notes: | |

| - --source-url must be a saved-view URL (?nw=<id>). Personal/default | |
| workspace URLs (?nw=nwuser<username>) are not supported by the underlying | |

| wandb-workspaces SDK | | | - The destination project is auto-bootstrapped with a placeholder run if it | | | doesn't exist yet, because the GraphQL upsertView mutation requires the | | | project to exist server-side. | | | """ | | | import argparse | | | import copy | | | import os | | | import sys | | | import wandb | | | import wandb_workspaces.workspaces as ws | | | def ensure_project_exists(entity: str, project: str): | | | """Make sure the destination project exists server-side. | | | Workspace.save() upserts the view via GraphQL but returns 404 if the | | | target project hasn't actually been provisioned. api.create_project and | | | api.project() aren't always sufficient — initializing a tiny run is the | | | most reliable way to guarantee the project exists before we upsert a view | | | into it. | | | """ | | | api = wandb.Api() | | | try: | |
