PtCrop

Crops a PyTorch tensor to the specified size. The input tensor must have a shape of (c, h, w) or (b, c, h, w). In ComfyUI Analysis, the tensor data type is "TENSOR," while in ComfyUI, the type "IMAGE" is used. To pass image data from ComfyUI to a ComfyUI Analysis node (e.g., this interpolation node), first use the "Pt From Image" node to convert it to a tensor, then transpose the axes from (b, h, w, c) to (b, c, h, w) before passing it to this node. This transposition can be performed using the "Pt Permute" node with (0, 2, 3, 1). To convert the output back to an image, apply "Pt Permute" with (0, 3, 1, 2) and then use the "Pt To Image" node. | Name | Data type | |---|---| | tens | Tensor | | height | Int | | width | Int | | Data type | |---| | Tensor | Category: PyTorch wrapper - Image processing ComfyUI Pt Wrapper Node Reference. © 2025 Hide Inada (HowToSD.com).

PtGather

Generates a tensor based on the index tensor using PyTorch's gather function. Specify the dim field using an integer to indicate the axis along which to gather elements. Each input tensor element is selected based on the index tensor. For example, consider the following input tensor: and the corresponding index tensor: If dim = 0, the function scans row-wise, treating each index value as a row index. If dim = 1, it scans column-wise, interpreting each index value as a column index. Let's analyze the case where dim = 1: Start at row 0, column 0. The index at this position is index[0, 0] = 0. PyTorch selects the value at position 0 from the array [10, 20, 30, 40, 50], which is 10. The result at this stage is: Moving to column 1: index[0, 1] = 4. The value at index 4 in [10, 20, 30, 40, 50] is 50. The updated result is: Repeating this process for all elements constructs the final gathered tensor. | Name | Data type | |---|---| | tens | Tensor | | dim | Int | | index | String | | Data type | |---| | Tensor | Category: PyTorch wrapper - Indexing and Slicing Operations ComfyUI Pt Wrapper Node Reference. © 2025 Hide Inada (HowToSD.com).

PtInterpolateByScaleFactor

Resizes a PyTorch tensor using interpolation by scale factor. The input tensor must have a shape of (c, h, w) or (b, c, h, w). In ComfyUI Analysis, the tensor data type is "TENSOR," while in ComfyUI, the type "IMAGE" is used. To pass image data from ComfyUI to a ComfyUI Analysis node (e.g., this interpolation node), first use the "Pt From Image" node to convert it to a tensor, then transpose the axes from (b, h, w, c) to (b, c, h, w) before passing it to this node. This transposition can be performed using the "Pt Permute" node with (0, 2, 3, 1). To convert the output back to an image, apply "Pt Permute" with (0, 3, 1, 2) and then use the "Pt To Image" node. | Name | Data type | |---|---| | tens | Tensor | | scalefactor | Float | | mode | | | Data type | |---| | Tensor | Category: PyTorch wrapper - Image processing ComfyUI Pt Wrapper Node Reference. © 2025 Hide Inada (HowToSD.com).
