我正在使用Scapy的pdfdump方法生成数据包的PDF：
from scapy.layers.inet import ICMP, IP
packet = IP(dst="192.168.111.1") / ICMP()
packet.pdfdump("report.pdf")
执行此代码时，会从PyX库中打印出许多消息。

有没有办法禁用或抑制这些消息，这样它们就不会打印出来？PyX手册中没有太多关于如何调整这些消息的冗长程度的内容。
此输出是在日志记录级别使用标准python日志记录框架创建的。信息。默认情况下，此类日志记录输出是静音的，因为默认情况下是日志记录。警告(IIRC(。不管怎样，只要调整你的日志记录级别，就可以防止通知打扰你。此外，您还可以查看pyxinfo调用，它是PyX提供的用于启用此输出的解决方案。(也许这是您正在使用的库在某个地方调用的，您想禁用它。(注意，PyX的这种行为也在http://pyx.sourceforge.net/manual/text.html#debugging
