通过 python (Flask) 从 GCS 读取和写入图像
Read and write images from GCS via python (Flask)
在本地机器上,我能够提取图像的特征并将相应的 .npy 文件存储在不同的文件夹中。
from PIL import Image
from feature_extractor import FeatureExtractor
from pathlib import Path
import numpy as np
if __name__ == '__main__':
fe = FeatureExtractor()
for img_path in sorted(Path("./static/img").glob("*.jpg")):
print(img_path) # e.g., ./static/img/xxx.jpg
feature = fe.extract(img=Image.open(img_path))
feature_path = Path("./static/feature") / (img_path.stem + ".npy") # e.g., ./static/feature/xyz.npy
np.save(feature_path, feature)
现在我想在 google 云中托管它。但是为此,我需要从 Google Cloud Storage 读取和写入图像。有没有类似 Path for GCS 的库?
这个有官方客户端库
pip install --upgrade google-cloud-storage

如果您想列出 GCS 存储桶中的苍蝇:
from google.cloud import storage
client = storage.Client()
for blob in client.list_blobs('bucketname', prefix='abc/myfolder'):
print(str(blob))
