jagandecapri / pad_packed_demo.py

Created September 3, 2021 12:20 — forked from HarshTrivedi/pad_packed_demo.py

Minimal tutorial on packing (pack_padded_sequence) and unpacking (pad_packed_sequence) sequences in pytorch.

	import torch
	from torch import LongTensor
	from torch.nn import Embedding, LSTM
	from torch.autograd import Variable
	from torch.nn.utils.rnn import pack_padded_sequence, pad_packed_sequence

	## We want to run LSTM on a batch of 3 character sequences ['long_str', 'tiny', 'medium']
	#
	# Step 1: Construct Vocabulary
	# Step 2: Load indexed data (list of instances, where each instance is list of character indices)

jagandecapri / force.reqanimframe.js

Created April 30, 2024 21:17 — forked from iros/force.reqanimframe.js

force layout with d3.timer instead of tick loop

	var force = d3.layout.force()
	.charge(-150)
	.linkDistance(30)
	.size([width, height]);

	d3.json("assets/500nodes.json", function(error, graph) {
	if (error) throw error;

	// Task 2:
	// Connect the force layout to the nodes and links in our dataset
