问题 I'm trying to annotate images with COCO key points for pose estimation using https://github.com/jsbroks/coco-annotator. As described in the Installation section I cloned the repo. I installed Docker and Docker-compose. Following this I started the container with $ docker-compose up and it is running. I am now on the website https://annotator.justinbrooks.ca/, I created one user and datasets but they do not appear in the repo datasets/ folder. I tried to create them manually and to load images

Preserving DataRowState when serializing DataSet using DataContractSerializer

给你一囗甜甜゛ 提交于 2021-01-27 19:54:40
问题 For various reasons I am having to send a typed dataset to a WCF service endpoint. This works fine except that upon Deserializing, the RowState of each row in each DataTable is set to 'Added', regardless of what they were on the client. If I write the serialized stream out to a file, I see that the RowState is not part of the Serialized data. How can I add this so that I can preserve the RowState across service boundaries? Not that I think it matters, but the client process is running .net 3

Could Keras prefetch data like tensorflow Dataset?

问题 In TensorFlow's Dataset API, we can use dataset.prefetch(buffer_size=xxx) to preload other batches' data while GPU is processing the current batch's data, therefore, I can make full use of GPU. I'm going to use Keras, and wonder if keras has a similar API for me to make full use of GPU, instead of serial execution: read batch 0->process batch 0->read batch 1-> process batch 1-> ... I briefly looked through the keras API and did not see a description of the prefetch. 回答1: If you call fit

问题 I have read numerous threads on similar topics on the forum. However, what I am asking here, I believe, it is not a duplicate question. I am reading a very large dataset (22 gb) of CSV format, having 350 million rows. I am trying to read the dataset in chunks, based on the solution provided by that link. My current code is as following. import pandas as pd def Group_ID_Company(chunk_of_dataset): return chunk_of_dataset.groupby(['id', 'company'])[['purchasequantity', 'purchaseamount']].sum()

One Hot Encoding with multiple tags in the column

问题 I have a simple dataset. id,question,category,tags,day,quarter,group_id 1,What is your name,Introduction,Introduction,1,3,0 2,What is your name,Introduction,"Introduction, work",1,3,1 Now if you see, in the tags column there are multiple inputs seperated by commas. If I try to one-hot-encode using pandas get_dummies function I will get that as a single column. But I wanted to create columns for each tags. How can I do that possibly? 回答1: I believe need str.get_dummies: df1 = df['tags'].str
