PTP capability check

hello,

I use PTP in my reserved VMs for better time precision. I used the following script

nodes = slice.get_nodes()
for node in nodes:
print (f”{node.get_name()} is hosted on {node.get_host()}”)
ad = fablib.get_site_advertisement(node.get_site())
print (f”PTP Capable: { ad.flags.ptp}\n”)

and I get the error

AttributeError                            Traceback (most recent call last)
Cell In[21], line 4
      1 nodes = slice.get_nodes()
      2 for node in nodes:
      3     print (f"{node.get_name()} is hosted on {node.get_host()}")
----> 4     ad = fablib.get_site_advertisement(node.get_site())
      5     print (f"PTP Capable: { ad.flags.ptp}\n")

AttributeError: 'FablibManager' object has no attribute 'get_site_advertisement'

these scripts worked for me earlier. because of this error I am unable to install the required software 

thanks
