GloVe word-embeddings Google colaboratory

Step 1: Importing necessary libraries and mounting Google Drive

To use GloVe word embeddings in Google Colaboratory, we need to import the necessary libraries and mount our Google Drive so that we can access the GloVe embeddings file.

import (
    "os"
    "io"
    "log"
    "path/filepath"
    "github.com/golang/glog"
    "golang.org/x/oauth2/google"
    "google.golang.org/api/drive/v3"
    "google.golang.org/api/option"
    "github.com/machinebox/sdk-go/textbox"
    "github.com/hajimehoshi/oto"
    "github.com/google/go-github/github"
)

Step 2: Authenticating and setting up Google Drive API

To authenticate and access the Google Drive API, we need to set up the necessary credentials and create a client.

func getClient(ctx context.Context, config oauth2.Config) http.Client {
    tokFile := tokenFile(config.TokenCacheDir, "drive-go-quickstart.json")
    tok, err := tokenFromFile(tokFile)
    if err != nil {
        tok = getTokenFromWeb(config)
        saveToken(tokFile, tok)
    }
    return config.Client(ctx, tok)
}

Step 3: Downloading GloVe embeddings file from Google Drive

Once we have authenticated and set up the Google Drive API, we can use it to download the GloVe embeddings file. We need to provide the file ID of the embeddings file and the path where we want to save it.

func downloadFile(client *http.Client, fileId string, destPath string) error {
    resp, err := client.Get("https://www.googleapis.com/drive/v3/files/" + fileId + "?alt=media")
    if err != nil {
        return err
    }
    defer resp.Body.Close()
    out, err := os.Create(destPath)
    if err != nil {
        return err
    }
    defer out.Close()
    _, err = io.Copy(out, resp.Body)
    if err != nil {
        return err
    }
    return nil
}

Step 4: Loading GloVe embeddings

After downloading the GloVe embeddings file, we can load it into memory and use it for word embedding tasks.

func loadGloveEmbeddings(embeddingsPath string) (map[string][]float64, error) {
    embeddings := make(map[string][]float64)
    file, err := os.Open(embeddingsPath)
    if err != nil {
        return nil, err
    }
    defer file.Close()
    scanner := bufio.NewScanner(file)
    for scanner.Scan() {
        line := scanner.Text()
        fields := strings.Fields(line)
        word := fields[0]
        embedding := make([]float64, len(fields)-1)
        for i, field := range fields[1:] {
            value, err := strconv.ParseFloat(field, 64)
            if err != nil {
                return nil, err
            }
            embedding[i] = value
        }
        embeddings[word] = embedding
    }
    if err := scanner.Err(); err != nil {
        return nil, err
    }
    return embeddings, nil
}

These are the steps involved in using GloVe word embeddings in Google Colaboratory. By following these steps, you can import the necessary libraries, authenticate and set up the Google Drive API, download the GloVe embeddings file, and load the embeddings into memory for further use in your Go code.
