AttributeError: 'IntervalArray' object has no attribute '_dtype' while reading pickle file to dataframe

I want to read a pickle file into a data frame. However, I get the following error message and I don't know how to solve the issue.
df_batches = pd.read_pickle(folder_in / "batches_and_phases.p")

Issues with loading .s2p file in python notebook using scikit-rf

Hi i am having issues with loading the .s2p file
when i ran the following code
import skrf as rf
from skrf import Network, Frequency
data1 = rf.Network('/Users/pradeeps/Desktop/Project/meas2018_07_06/300MHzNLOSX1DPS.s2p')
It showed the following error as shown below

As shown in this particular code i used scikit-rf is there any other package that i should use in this particular instance or am i doing anything wrong.
Thank you

You are probably missing permissions with your configured service account. Make sure the account has access to ad-manager and scopes are configured properly.

I suggest to do it this way:
class Adx:
def __init__(self):
self.GOOGLEADS_YAML = 'googleads.yaml'
self.GOOGLEADS_VERSION = 'v202111'
self.google_keys = self.GOOGLEADS_YAML
def activate(self):
ad_manager_client = ad_manager.AdManagerClient.LoadFromStorage(self.google_keys)

Getting error while converting Audio into Text in Python

I am trying to convert an Audio file to text . Audio is saved as Wel.wav in my desktop.
Below is the code:
import speech_recognition as sr
r = sr.Recognizer()

with sr.AudioFile(audio) as source:
audio = r.record(source)
print ('Done!')
try:
text = r.recognize_google(audio)
print (text)
except Exception as e:
print (e)
I am getting the below error:

There is an OS error preceding which appears to be the primary cause. I am not sure why this error arises. The .h5 filename keeps changing. With due research, I have suggestions that this could be a environmental variable issue and requires reinstall.
But am not sure the right method for debug. I am using WIN 10, with python 3.6.5, and jupyter 4.4.0
