fix

Run pip install g42cloudsdkevs.

error ImportError: cannot import name 'EvsClient' from 'huaweicloudsdkevs' ↓

cause Using wrong import path from the Huawei Cloud SDK instead of G42 SDK.

error huaweicloudsdkcore.exceptions.exceptions.ServiceResponseException: service error: AuthFailure ↓

cause Invalid or expired credentials (AK/SK) or wrong project ID.

Verify G42_AK, G42_SK, and G42_PROJECT_ID environment variables are set correctly.

Warnings

gotcha The library name is 'g42cloudsdkevs' not 'g42cloudsdk-evs' or 'g42cloud-evssdk'. Install via pip install g42cloudsdkevs exactly. ↓

fix Use `pip install g42cloudsdkevs`.

gotcha The package depends on huaweicloudsdkcore for base classes and authentication. It must be installed separately or as a dependency. ↓

fix Install huaweicloudsdkcore: `pip install huaweicloudsdkcore`.

Imports

EvsClient

from huaweicloudsdkcore.client import ClientBuilder
from g42cloudsdkevs.v1 import EvsClient
from g42cloudsdkevs.v1.model import *

Correct import pattern for EVS client and models.

CreateVolumeRequest

wrong

from huaweicloudsdkevs import CreateVolumeRequest

correct

from g42cloudsdkevs.v1.model import CreateVolumeRequest

Wrong package prefix; must use g42cloudsdkevs, not huaweicloudsdkevs.

Quickstart

Initializes EVS client and lists volumes. Requires environment variables for authentication.

from huaweicloudsdkcore.auth.credentials import BasicCredentials
from huaweicloudsdkcore.client import ClientBuilder
from g42cloudsdkevs.v1 import EvsClient
from g42cloudsdkevs.v1.model import ListVolumesRequest

ak = os.environ.get('G42_AK', '')
sk = os.environ.get('G42_SK', '')
project_id = os.environ.get('G42_PROJECT_ID', '')

credentials = BasicCredentials(ak, sk, project_id)
client = EvsClient.new_builder() \
    .with_credentials(credentials) \
    .with_endpoint('https://evs.g42cloud.com') \
    .with_region('global') \
    .build()

req = ListVolumesRequest()
resp = client.list_volumes(req)
print(resp)
