Inspect Your Tensors
Load NumPy and PyTorch tensor files and review shapes, dtypes, storage order, and metadata at a glance.
Visualize tensors to confirm patterns, and hover to inspect exact values and indices.
Hover stats include min/max, mean ± std, and counts of zeros, NaNs, and ±Infs.
Slice, Dice & Review
Choose x/y axes, tile extra dimensions, and flip channels-first/last layouts when auto-detection is wrong.
Configure which dimensions are sliced by index versus tiled, and reshape into new tensors.
NaN and Inf values render in high-contrast colors so anomalies stand out.
Compare Related Tensors
Use Page Up/Down to step through tensors, or Shift+Page Up/Down to jump to the next compatible view size for a visual diff.
Keep the same layout to compare tiles, slices, and channel order side by side.
Extract What You Need
Open NPZ or PT bundles, select just the tensors you need, and export them as individual NPY files.
Apply reshapes before export, without materializing full tensors in memory.
Navigate in Detail
Pan and zoom in tile space to inspect fine structure, or jump to fit and 1:1 zoom.
Arrow keys select slice dimensions (up/down) and adjust slice indices (left/right).
