nn-calc 0.1.1

A calculator for encoder and decoder layers of any neural networks

Neural Network calculator

Neural Network calculator reads your hyperparameter choices (kernel size, stride, channels, etc.) and outputs:

• Encoder block: detailed Conv2d specs + parameter counts

• Decoder block: mirrored ConvTranspose2d specs + parameter counts

• Recurrent stacks: per-layer (input_size, hidden_size, params) for RNN/GRU/LSTM

Features:

• Multi-layer CNN mode

  • Global defaults or per-layer overrides for stride, kernel size, padding

  • Automatic channel-chaining in encoder → mirrored decoder block

• Recurrent mode

  • RNN: single-gate formula

  • GRU: 3× single-gate formula

  • LSTM: 4× single-gate formula

  • Stacked layers automatically chain hidden sizes

• User-friendly CLI with automatic help pages & type-safe options

• Subcommand support, lazy loading, file arguments, and more via Click

Usage:

Example

bash command

nn_calc -h

output

  Calculate parameter counts for CNN encoder/decoder OR RNN/GRU/LSTM layers.

Options:
  --model [cnn|rnn|gru|lstm]  Type of network to compute parameters for.
                              [default: cnn]
  -n, --num-layers INTEGER    Number of layers (CNN) or RNN layers
                              (recurrent).  [default: 3]
  --stride INTEGER            Default stride for each conv layer.  [default:
                              1]
  --kernel-size INTEGER       Default kernel size for each conv layer.
                              [default: 3]
  --padding INTEGER           Default padding for each conv layer.  [default:
                              1]
  --in-channels INTEGER       CNN: input channels for first layer; RNN: input
                              size.  [default: 3]
  --out-channels INTEGER      CNN: output channels for each layer; RNN: hidden
                              size.  [default: 64]
  -S, --strides INTEGER       CNN: per-layer strides (e.g. -S 1 2 2).
  -K, --kernel-sizes INTEGER  CNN: per-layer kernel sizes.
  -P, --paddings INTEGER      CNN: per-layer paddings.
  -h, --help                  Show this message and exit.
