Log keyword: No module named 'pytorch_lightning'
Different projects and revisions may use different namespaces. Installing either distribution is not automatically sufficient for every consumer, and checkpoint errors are not simply missing-package errors.
Log keyword: No module named 'rotary_embedding_torch'
A missing positional-encoding implementation is not a missing weight file. Once import works, inspect the API and tensor contract used by the actual model.
Log keyword: No module named 'hydra'
Hydra's common distribution name differs from its import name. A missing module and a missing configuration require separate repairs.
Log keyword: No module named 'deepdiff'
A configuration node may fail while importing DeepDiff, comparing an object or presenting its result. A reported difference is normally data, not a dependency failure.
Log keyword: No module named 'decord'
Check the Python binding, media input and native decoding capability separately. CUDA availability in Torch does not establish GPU decoding support in Decord.
Log keyword: No module named 'nvvfx'
The import may belong to a node-specific wrapper or native SDK binding. One log line does not identify a trusted, compatible distribution on a package index.
Log keyword: No module named 'webcolors'
An AttributeError in a color node may concern an old mapping, not a missing module. Identify the exception before choosing a package repair.
Log keyword: No module named 'timm'
A node imports the library, chooses an implementation and may then obtain pretrained weights. Determine which stage failed instead of treating every message as a missing package.
Log keyword: No module named 'blend_modes'
Separate a missing library from an operation receiving the wrong image representation. Channel count, numeric range and opacity deserve their own checks.
Log keyword: No module named 'soundfile'
Check import, native-library loading and file decoding in that order. Installing FFmpeg does not establish that every dependency of SoundFile is available.
Log keyword: No module named 'OpenGL_accelerate'
Rendering nodes can depend on a Python binding, an acceleration extension and a usable graphics context. Locate the failing layer before changing packages or graphics settings.
Log keyword: No module named 'flash_attn'
A missing import or failed wheel build is not a reason to replace Torch immediately. Establish which FlashAttention implementation the node needs and whether your platform can provide it.
Log keyword: No module named 'dlib'
A face-processing node may have no usable Python binding or may have failed while building native code. Do not assemble an environment from unidentified DLLs or wheels.
Log keyword: No module named 'argostranslate'
A translation node can fail before the Python package imports or after import when it looks for a language model. Confirm that the node actually uses Argos Translate before installing anything.
Log keyword: Windows protected your PC
First establish which security feature blocked which file. A familiar filename is not proof that a download is the publisher's original release.
Log keyword: File name too long
An extraction, Git checkout or node build can fail because of one long path. Identify the failing tool before changing system policy or relocating an existing Python environment.
Log keyword: CRC Failed
CRC errors, Data Error and an unrecognized archive do not all have the same cause. Do not start a partially extracted Python environment while the integrity of its files remains unknown.
Log keyword: No module named mmcv
Distinguish full and lite distributions, source-build failures and runtime extension loading.
Log keyword: No module named sqlalchemy
Separate missing libraries, database access and migration state without deleting the database.
Log keyword: No module named segment_anything
Identify the implementation required by the node before replacing segmentation packages or checkpoints.
Log keyword: No module named simpleeval
Check the dependency first, then the expression and allowed operations exposed by the node.
Log keyword: No module named transformers
Locate the failing stage before changing Transformers, model files or network settings.
Log keyword: No module named scipy
Keep the precise import and operation errors instead of treating every scientific-library failure as an install issue.
Log keyword: No module named av
Check PyAV, its linked libraries and an external FFmpeg executable as separate dependencies.
