crewai框架出现SSLError

使用crewai框架（0.102.0）的时候，控制台突然会出现很多报错信息，但是并不影响程序的实际输出

ERROR:opentelemetry.sdk.trace.export:Exception while exporting Span batch.

看上去不是自己代码的问题，翻了一下官方GitHub仓库里ISSUE的回复

有两种解决办法，添加如下代码

from crewai.telemetry import Telemetry

def noop(*args, **kwargs):
print("Telemetry method called and noop'd\n")
pass

for attr in dir(Telemetry):
if callable(getattr(Telemetry, attr)) and not attr.startswith("__"):
setattr(Telemetry, attr, noop)

或者在顶部添加环境变量

os.environ["OTEL_SDK_DISABLED"] = "true"

我使用的是第二种，确实没有报错了，舒服多了！
