epycloud download

Download output plots from Google Cloud Storage.

Usage

epycloud download [OPTIONS]

Description

Downloads specific output files (plots, CSVs) from experiment runs in GCS. Automatically selects the latest run for each matched experiment and presents a confirmation screen before downloading.

Options

Option Type Description Default
-e, --exp-filter PATTERN Required Glob pattern to match experiment paths (fnmatch) -
-o, --output-dir DIR Optional Output directory ./downloads
--name-format {long,short} Optional Filename format long
--nest-runs Flag Add {run_id}/ subdirectory under each experiment Disabled
--bucket BUCKET Optional GCS bucket name From config
--dir-prefix PREFIX Optional GCS directory prefix From config
-y, --yes Flag Skip confirmation prompt Disabled

Name Formats

  • long (default): Flattened GCS path as filename (e.g., experiment-name__output__plot.png). Avoids collisions when downloading from multiple experiments.
  • short: Original basename only (e.g., plot.png). Shorter but may collide across experiments.

Examples

# Download plots for all experiments in a month
epycloud download -e "202607/"

# Download for a specific experiment pattern
epycloud download -e "202607/hosp_*"

# Custom output directory
epycloud download -e "202607/" -o ./results

# Short filenames with run subdirectories
epycloud download -e "202607/" --name-format short --nest-runs

# Skip confirmation
epycloud download -e "202607/" -y

# Pipe-friendly: data output on stdout, progress on stderr
epycloud download -e "202607/" 2>/dev/null

Output Directory Structure

Default (--name-format long):

epycloud download -e "202607/"

downloads/
├── 202607/exp1/
│   ├── 202607_exp1_20260218-..._outputs_..._posterior_grid.pdf
│   └── 202607_exp1_20260218-..._outputs_..._quantiles_grid_sidebyside.pdf

    └── 202607_hosp_exp2_20260217-..._outputs_..._categorical_rate_trends.pdf

Long names flatten the GCS path (with dir_prefix stripped) into the filename using _, so each file is unique even if multiple experiments share the same output filenames.

--name-format short:

epycloud download -e "202607/" --name-format short

downloads/
└── 202607/exp1/
    ├── posterior_grid.pdf
    └── quantiles_grid_sidebyside.pdf

--name-format short --nest-runs:

epycloud download -e "202607/" --name-format short --nest-runs

downloads/
└── 202607/exp1/
    └── 20260218-143015-a1b2c3d4/
        ├── posterior_grid.pdf
        └── quantiles_grid_sidebyside.pdf

Experiments starting with hosp_ also download categorical_rate_trends.pdf.

Workflow

  1. Search: Scans GCS for experiments matching the pattern
  2. Resolve: Finds the latest run ID for each matched experiment
  3. Plan: Shows a download plan with file counts and run details
  4. Confirm: Prompts for confirmation (skip with -y)
  5. Download: Downloads files and reports per-experiment results

Exit Codes

0 Success
1 Error (GCS error, download failure)
