为什么gdal对MODIS光栅图像返回“无”，如何正确加载？

Question

我有一个简单的kmeans示例，我正试图在GoogleColab中使用它，但现在GoogleDrive无法正确加载到我的Geotiff中。我使用gdal的方式是否有问题？谢谢

### mount google drive
from google.colab import drive
from sklearn.cluster import KMeans 
import os
from osgeo import gdal
import numpy as np 

drive.mount('/content/gdrive')
!ls

output: Drive already mounted at /content/gdrive; to attempt to forcibly remount, call drive.mount("/content/gdrive", force_remount=True). gdrive sample_data

### load image
naip_fn = './gdrive/MOD13A1.006__500m_16_days_EVI_doy2021065_aid0001.tif' 
driverTiff = gdal.GetDriverByName('GTiff') 
image = gdal.Open(naip_fn,gdal.GA_ReadOnly) 
print(image)

output: None

Answer 1

原来这只是谷歌硬盘路径的问题。从Google Drive加载数据时，需要我的硬盘部分，即

naip_fn = './gdrive/My Drive/MOD13A1.006__500m_16_days_EVI_doy2021065_aid0001.tif'
