# Pt Crop
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.

# Pt Gather
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:
```
[ [10, 20, 30, 40, 50],
[100, 200, 300, 400, 500]]
```
and the corresponding index tensor:
```
[ [0, 4, 3, 2, 0],
[4, 3, 0, 0, 0]]
```
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:
```
[[10, ?, ?, ?, ?]
[?, ?, ?, ?, ?]]
```
* 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:
```
[[10, 50, ?, ?, ?]
[?, ?, ?, ?, ?]]
```
* Repeating this process for all elements constructs the final gathered tensor.

# Ptn Conv Model
A convolutional model consisting of multiple convolutional layers.
### Fields:
- `input_dim`: A string representing the input dimensions in the format "(C,H,W)".
Example: `"(3,28,28)"` for a 3-channel 28x28 image.
- `penultimate_dim`: An integer specifying the number of features before the output layer. If you specify 0, the number is computed internally.
Default: `0`
- `output_dim`: An integer specifying the number of output features, which should match the number of target classes in classification.
Default: `10`, Min: `1`, Max: `1e6`.
- `channel_list`: A string representing a Python list of integers specifying the number of channels per layer excluding the channel for the input (e.g. 3 for the color image).
Example: `"[32,64,128,256,512]"`.
- `kernel_size_list`: A string representing a Python list of kernel sizes per layer.
Example: `"[3,3,3,3,1]"`.
- `padding_list`: A string representing a Python list of padding values per layer.
Example: `"[1,1,1,1,0]"`.
- `downsample_list`: A string representing a Python list of boolean values indicating whether to downsample at each layer.
Example: `"[True,True,True,True,False]"`.
