我是Python的超级初学者，我正在尝试做Coursera课程中的一个作业。我需要编写一个简单的代码，通过IBM沃森Translate连接并给予结果。到目前为止，根据说明，我已经创建了一个.env文件，其中包含Watson服务的apikey和url，然后我创建了另一个文件来翻译文本，如下所示：

import json
from ibm_watson import LanguageTranslatorV3
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator
import os
from dotenv import load_dotenv

load_dotenv()

apikey = os.environ['apikey']
url = os.environ['url']

# Setup service
authenticator = IAMAuthenticator(apikey)
lt = LanguageTranslatorV3(version='2018-05-01', authenticator=authenticator)
lt.set_service_url(url)

translation = lt.translate(text='We are sinking.', model_id='en-de').get_result()
translation
translation['translations'][0]['translation']

此外，在测试代码之前，我已经运行了这些命令，以便按照指令加载库：

python3 -m pip install python-dotenv
python3 -m pip install ibm_watson
python3 -m pip install Flask

我遇到的错误是：

Traceback (most recent call last):   File "translator.py", line 14, in <module>
