我对 Python 很陌生。我正在试用 Amazon Polly 文本转语音模块。我在 Windows 10 上运行它。已经阅读了亚马逊文档，但我现在很迷茫。对不起，我的英语不是很好。
我的代码如下。
"""Getting Started Example for Python 2.7+/3.3+"""
from boto3 import Session
from botocore.exceptions import BotoCoreError, ClientError
from contextlib import closing
import os
import sys
import subprocess
from tempfile import gettempdir
# Create a client using the credentials and region defined in the [adminuser]
# section of the AWS credentials file (~/.aws/credentials).
session = Session(profile_name="adminuser")
polly = session.client("polly")
try:
# Request speech synthesis
response = polly.synthesize_speech(Text="Hello world!", OutputFormat="mp3",
VoiceId="Joanna")
except (BotoCoreError, ClientError) as error:
# The service returned an error, exit gracefully
print(error)
sys.exit(-1)
# Access the audio stream from the response
if "AudioStream" in response:
# Note: Closing the stream is important as the service throttles on the
# number of parallel connections. Here we are using contextlib.closing to
# ensure the close method of the stream object will be called automatically
# at the end of the with statement's scope.
with closing(response["AudioStream"]) as stream:
output = os.path.join(gettempdir(), "speech.mp3")
try:
# Open a file for writing the output as a binary stream
with open(output, "wb") as file:
file.write(stream.read())
except IOError as error:
print(error)
sys.exit(-1)
else:
# The response didn't contain audio data, exit gracefully
print("Could not stream audio")
sys.exit(-1)
# Play the audio using the platform's default player
if sys.platform == "win32":
os.startfile(output)
else:
# the following works on Mac and Linux. (Darwin = mac, xdg-open = linux).
opener = "open" if sys.platform == "darwin" else "xdg-open"
subprocess.call([opener, output])
我在这里有我的凭证文件。（对此进行了编辑，因此它不是真正的凭据）。在同一文件夹中，它被保存为配置。我还在同一个文件夹中制作了名为 config 和 boto.config 的副本，希望我把名字弄错了。但无济于事。
[Credentials]
aws_access_key_id = AKIAIO4GAFVCGZMTZ6WQ
aws_secret_access_key = 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
[adminuser]
aws_access_key_id = AKIAIO4GAFVCGZMTZ6WQ
aws_secret_access_key = /7KVymkCQbGKI5/E1ifdafsuVCciwOd1WiIImxA
这是我得到的错误信息。

有没有专家告诉我我应该大致做什么？
