Following instructions from here https://docs.microsoft.com/en-us/power-bi/desktop-python-scripts
I can run the following python code and generate data.
import pandas as pd data = [['Alex',10],['Bob',12],['Clarke',13]]
df = pd.DataFrame(data,columns=['Name','Age'],dtype=float)
print (df)
I contructed same df in a class - created a package named Mypackage
import pandas as pd
class Mydata:
def __init__(self):
pass
def main_page(self):
data = [['Alex',10],['Bob',12],['Clarke',13]]
df = pd.DataFrame(data,columns=['Name','Age'],dtype=float)
return df
Now when I call the data, nothing is returned
from Mypackage import MyData
df = Mydata().main_page()
print(df)
If I try
from Mypackage import MyData
df = Mydata().main_page()
print(df.head())
Then I get the following error
Unable to connect
Details: "ADO.NET: Python script error.
Traceback (most recent call last):
File "PythonScriptWrapper.PY", line 13, in <module>
print(df.head())
AttributeError: 'NoneType' object has no attribute 'head'
"

Hi @vasimnps ,
What the version of Python do you install? If you use 3.7, please install Python 3.6 to have a try. And make sure you have installed Pandas package.
