I have read shapefile in a zip format from my S3 bucket successfully through geopandas, but I get error when trying to output the same geodataframe as a shapefile to the same S3 bucket.
The code below is how I read the zip file, and it works nicely:
## session for connecting to S3
session = boto3.session.Session(aws_access_key_id='MY-KEY-ID',
aws_secret_access_key='MY-KEY')
s3 = session.resource('s3')
bucket = s3.Bucket('my_bucket')
## read shapefile
TPG = bucket.Object(key='/shapefiles/grid.zip')
TPGrid = geopandas.read_file(TPG.get()['Body'])
But when I tried to output the same geodataframe like this:
TPGrid.to_file(filename='s3://my_bucket/output/TPGrid.zip', driver='ESRI Shapefile')
I will get error code:
ERROR:fiona._env:Only read-only mode is supported for /vsicurl

I have tried several ways, such as using '.csv' or '.shp', but not any one worked. I am using python 3.6 and packages below, hope these information will help:
- geopandas-0.9.0
- shapely-1.7.1
- fiona-1.8.20
- GDAL-3.2.3
I kept fighting with this problem all day.... Any help will be highly appreciated.
