Use `pad=True` for batches with variable shapes.\n\n## Prerequisites\n\n- To run or validate code, NVIDIA DALI must be installed with dynamic mode importable as `nvidia.dali.experimental.dynamic`.\n- GPU decode or GPU operators require a CUDA-capable DALI build and an available NVIDIA GPU/driver.\n- Framework conversion examples require the target framework installed, such as PyTorch for `.torch()`.\n\n## Introduction\n\nDynamic mode is DALI's imperative Python API. It lets code call DALI operators directly from normal Python control flow instead of building and running a pipeline graph.\n\n## Core Data Types\n\n### Tensor -- single sample\n\n```python\nt = ndd.tensor(data)           # copy\nt = ndd.as_tensor(data)        # wrap, no copy if possible\nt.cpu()                        # move to CPU\nt.gpu()                        # move to GPU\nt.torch(copy=False)            # conversion to PyTorch tensor with no copy (default)\nt[1:3]                         # slicing supported\nnp.asarray(t)                  # NumPy via __array__ (CPU only)\n```\n\nSupports `__dlpack__`, `__cuda_array_interface__`, `__array__`, arithmetic operators.\n\n### Batch -- collection of samples (variable shapes OK)\n\n```python\nb = ndd.batch([arr1, arr2])    # copy\nb = ndd.as_batch(data)         # wrap, no copy if possible\n```\n\n**Batch has no `__getitem__`** -- `batch[i]` raises `TypeError` because indexing is ambiguous (sample selection vs. per-sample slicing). Use the explicit APIs instead:\n\n| Intent | Method | Returns |\n|--------|--------|---------|\n| Get sample i | `batch.tensors[i]` | `Tensor` |\n| Get subset of samples | `batch.tensors[slice_or_list]` | `Batch` |\n| Slice within each sample | `batch.slice[...]` | `Batch` (same batch_size) |\n| Sample-wise slicing | `batch.slice[batch_of_indices]` | `Batch` (same batch_size) |\n\n`.tensors[]` picks **which samples**. `.slice` indexes **inside each sample**.\n\n```python\nxy = ndd.random.uniform(batch_size=16, range=[0, 1], shape=2)\ncrop_x = xy.slice[0]       # Batch of 16 scalars, first element from each sample\ncrop_y = xy.slice[1]       # Batch of 16 scalars, second element from each sample\nsample_0 = xy.tensors[0]   # Tensor, the entire first sample [x, y]\n```\n\n### Advanced slicing\n\nThe `.slice[]` API accepts batches of indices, allowing the user to mix and match batches and\nscalar values, e.g.:\n```python\nimgs = ndd.imread(filenames)  # a batch of images, if `filenames` is a list\nsliced = imgs.slice[\n    42 :  # the range start is broadcast to all samples\n    ndd.batch(imgs.shape).slice[0] // 2  # per-sample range stop (half of each image)\n]\n```\n\n**PyTorch conversion:**\n- `batch.torch()` -- works for uniform shapes; raises for ragged batches\n- `batch.torch(pad=True)` -- zero-pads ragged batches to max shape (use for variable-length audio, detection boxes, etc.)\n- `batch.torch(copy=None)` is the default (avoids copy if possible)\n- Batch has **no `__dlpack__`** -- use `ndd.as_tensor(batch)` first for DLPack consumers. `ndd.as_tensor` supports `pad` as well.\n- `Tensor.torch(copy=False)` is default (no copy)\n\n**Iteration:** `for sample in batch:` yields Tensors.\n\n## Readers\n\nReaders are **stateful objects** -- create once, reuse across epochs. This matters because readers track internal state like shuffle order and shard position.\n\n```python\nreader = ndd.readers.File(file_root=image_dir, random_shuffle=True)\n\nfor epoch in range(num_epochs):\n    for jpegs, labels in reader.next_epoch(batch_size=64):\n        # jpegs, labels are Batch objects\n        ...\n```\n\nKey points:\n- Reader outputs (jpegs, labels, etc.) are **CPU** tensors/batches. Labels typically stay on CPU until you convert them for your framework (e.g. `labels.torch().to(device)`).\n- Reader classes are **PascalCase**: `ndd.readers.File(...)`, `ndd.readers.COCO(...)`, `ndd.readers.TFRecord(...)`\n- `batch_size` goes to `next_epoch()`, not to the reader constructor\n- `next_epoch(batch_size=N)` yields tuples of `Batch`; `next_epoch()` without batch_size yields tuples of `Tensor`\n- The iterator from `next_epoch()` must be fully consumed before calling `next_epoch()` again\n- Once a reader is used with a given batch_size, it cannot be changed. Similarly, a reader used in batch mode cannot switch to sample mode or vice versa.\n\nSharded reading for distributed training:\n```python\nreader = ndd.readers.File(\n    file_root=image_dir,\n    shard_id=rank, num_shards=world_size,\n    stick_to_shard=True,\n    pad_last_batch=True,\n)\n```\n\n## Device Handling\n\n- Device is **inferred from inputs** -- GPU if any input is on GPU\n- For hybrid decode: use `device=\"gpu\"` (NOT `\"mixed\"`). The `\"mixed\"` keyword is a pipeline-mode concept for implicit CPU-to-GPU transfer; in dynamic mode, passing `device=\"gpu\"` triggers the same hardware-accelerated decode path.\n- Don't call `.cpu()` before passing to a GPU model -- `.torch()` gives you a GPU tensor directly. `.cpu()` is only needed for consumers requiring host memory (numpy, `__array__`).\n- CUDA stream sync between DALI and PyTorch is **automatic via DLPack** -- no manual stream management needed.\n\n## Execution Model\n\nDefault mode is `eager` -- async execution in a background thread, returns immediately.\n\n**No `.evaluate()` needed in most cases.** Any data consumption (`.torch()`, `__dlpack__`, `__array__`, `.shape`, property access, iteration) triggers evaluation automatically.\n\nFor debugging, switch to synchronous mode so errors surface at the exact call site rather than later in the async queue:\n\n```python\nwith ndd.EvalMode.sync_cpu:\n    images = ndd.decoders.image(jpegs, device=\"gpu\")\n    images = ndd.resize(images, size=[224, 224])\n    # Any error surfaces here, at the exact op that failed\n```\n\nModes (increasing synchronicity): `deferred` < `eager` < `sync_cpu` < `sync_full`\n\nUse `EvalMode.sync_full` for debugging instead of scattering `.evaluate()` calls -- it's cleaner and catches all issues at once. `sync_cpu` is often sufficient and lighter than `sync_full`.\n\n## Thread Configuration\n\n```python\nndd.set_num_threads(4)  # Call once at startup, only if necessary to override the defaults\n```\n\nControls DALI's internal worker threads for CPU operators. Defaults to CPU affinity count or `DALI_NUM_THREADS` env var. Unrelated to Python-level threading.\n\n## RNG\n\nTwo approaches (use one, not both):\n\n```python\n# Approach 1: set the thread-local default seed (simple, good enough for most cases)\nndd.random.set_seed(42)\nangles = ndd.random.uniform(batch_size=64, range=(-30, 30))\n\n# Approach 2: explicit RNG object (finer control, pass rng= to each op)\nrng = ndd.random.RNG(seed=42)\nvalues = ndd.random.uniform(batch_size=64, range=[0, 1], shape=2, rng=rng)\n```\n\nWhen `rng=` is passed to a random op, the explicit RNG overrides the default seed. Thread-local: each thread has independent random state.\n\nRandom ops need an explicit `batch_size` when working with batches -- there is no pipeline-level batch size to inherit.\n\n## Checkpointing\n\nDynamic mode has **no pipeline-level checkpoint**. Checkpoints aggregate the state of individual stateful objects: readers and `RNG` instances. Stateless ops (decoders, resize, rotate, normalize, ...) are not part of a checkpoint.\n\n```python\nckpt = ndd.checkpoint.Checkpoint()\nckpt.register(reader, \"my_reader\")\nckpt.register(rng, \"rng\")\n\n# ... iterate for a while ...\n\nckpt.collect()                       # snapshot the registered objects\nckpt.save(\"ckpt_{seq:04d}.json\")     # writes ckpt_0000.json, ckpt_0001.json, ...\n```\n\nRestoring is the symmetric operation -- build a *fresh* reader and `RNG`, then `load` + `register`. The loaded state is applied to each object at `register` time:\n\n```python\nreader = ndd.readers.File(file_root=..., enable_checkpointing=True, name=\"my_reader\")\nrng = ndd.random.RNG()\n\nckpt = ndd.checkpoint.Checkpoint()\nckpt.load(\"ckpt_{seq:04d}.json\")     # picks the highest sequence number\nckpt.register(reader, \"my_reader\")   # state applied here\nckpt.register(rng, \"rng\")            # ditto\n\nfor batch in reader.next_epoch(batch_size=N):\n    ...  # produces the next batch after the checkpointed iteration\n```\n\nKey rules:\n\n- **Readers must opt in.** Construct with `enable_checkpointing=True`. Registering an already-iterated reader without it raises `RuntimeError`; if the reader has not been iterated yet, `register` enables it retroactively.\n- **Reader state must be applied before the first `next_epoch` call.** The prefetch thread starts on first iteration and the snapshot queue is locked after that. `set_state` (or a `register` from a loaded checkpoint) on an already-iterated reader raises `RuntimeError`.\n- **`enable_checkpointing=True` is incompatible with `compile=True`.** Calling `reader.next_epoch(..., compile=True)` on a checkpointing-enabled reader raises `NotImplementedError`.\n- **Named registration is safer.** Anonymous `register(op)` uses sequential keys (`__op_0`, `__op_1`, ...) so the registration order must match between save and restore. Type tags catch cross-type swaps but not reorders of compatible types. Prefer `register(op, name)`.\n- **`ndd.checkpoint.current()`** returns the `Checkpoint` bound to the current thread-local `EvalContext`. It's shared across calls -- call `ckpt.clear()` if reusing the default context for unrelated runs.\n- **Filename pattern:** `save`/`load` take a Python format string with a single `{seq}` placeholder (e.g. `\"ckpt_{seq:04d}.json\"`). `save` picks the next free sequence; `load` picks the highest matching one on disk.\n- **Format version is strict.** `deserialize` rejects payloads from a different checkpoint format version -- no automatic upgrade.\n- **Not thread-safe.** One `Checkpoint` per thread.\n\nManual `get_state` / `set_state` is also available directly on each `Reader` and `RNG` -- the `Checkpoint` aggregator is built on top of it. Use the manual API only when integrating with an external checkpoint system.\n\n## Examples\n\n### Image Classification Pipeline\n\n```python\nimport nvidia.dali.experimental.dynamic as ndd\n\nreader = ndd.readers.File(file_root=\"/data/imagenet/train\", random_shuffle=True)\n\nfor epoch in range(num_epochs):\n    for jpegs, labels in reader.next_epoch(batch_size=64):\n        images = ndd.decoders.image(jpegs, device=\"gpu\")\n        images = ndd.resize(images, size=[224, 224])\n        images = ndd.crop_mirror_normalize(\n            images,\n            mean=[0.485 * 255, 0.456 * 255, 0.406 * 255],\n            std=[0.229 * 255, 0.224 * 255, 0.225 * 255],\n        )\n        train_step(images.torch(), labels.torch())\n```\n\n## Common Mistakes\n\n| Wrong | Right | Why |\n|-------|-------|-----|\n| `device=\"mixed\"` | `device=\"gpu\"` | `\"mixed\"` is pipeline mode only |\n| `batch[i]` | `batch.tensors[i]` | `Batch` has no `__","tagline":"DALI imperative dynamic mode (`nvidia.dali.experimental.dynamic`, ndd): use when working on ndd code or migrating pipelines; skip pipeline-only tasks.","category":"coding-agents","tags":["agent-skill"],"author":"NVIDIA","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"recursive skill source sync","sourceDetail":"NVIDIA/skills","creatorName":"NVIDIA","creatorUrl":"https://github.com/NVIDIA","sourceUrl":"https://github.com/NVIDIA/skills/tree/main/skills/dali-dynamic-mode","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/nvidia-dali-dynamic-mode#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
