I am using pyshark for live packet capture. when I pass a parameter output_file = myFilObject for saving captures to a file,
getting following error on sniffing line. If output_file parameter is removed, this works absolutely fine. Please suggest.
MySampleCode:
import pyshark
def capturePacket():
outputF = open('capturepcap.pcap', 'w')
cap = pyshark.LiveCapture(interface='Ethernet 8', output_file=outputF)
cap.sniff(timeout=60)
outputF.close()

PS C:\Users\wxyz\Documents\automation\practice_set_script\paket_capture>
The issue in your code is these lines:
outputF = open('capturepcap.pcap', 'w')
cap = pyshark.LiveCapture(interface='Ethernet 8', output_file=outputF)
The output_file parameter is a string and not a io.TextIOWrapper
:param output_file: A string of a file to write every read packet into (useful when filtering).
So this works:
import pyshark
def capturePacket():
cap = pyshark.LiveCapture(interface='en0', output_file='capturepcap.pcap')
cap.sniff(timeout=60)
capturePacket()
Here is a reference that I put together on using PyShark
I am pretty new to blender, animations and gltf. I have successfully created my 3d model and was able to export that as glb file. Currently, I am trying to add a walking animation but the export to gltf with animations doesn't work. This is the error that the exporter is throwing:

I suppose that the gltf exporter can't find my keyframes, but I have no clue on how to fix that issue.
Any help is much appreciated!
Thanks
I have submitted a bug report for the gltf exporter. You can look at it here: https://github.com/KhronosGroup/glTF-Blender-IO/issues/1401
Removing invalid drivers fixes the issue.
I am trying to install numpy but it is giving this error please help what should I do ?
