I have a Python code by a multimeter manufacturer, that builds a data frame during the code duration to save voltage measurements. But I have errors

I have imported the libraries, connected the multimeter, but I encounter an error related to a writer function

How to mitigate Win32 problem with import module?

I am trying to write a df to a Word document by the following code:
import win32api
import win32
# data frame
wordApp = win32.gencache.EnsureDispatch('Word.Application')
wordApp.Visible = False
doc = wordApp.Documents.Open(os.getcwd()+'\\template.docx')
rng = doc.Bookmarks("PUTTABLEHERE").Range
# creating Table
# add one more row in table at word because you want to add column names as header
Table=rng.Tables.Add(rng,NumRows=df.shape[0]+1,NumColumns=df.shape[1])
for col in range(df.shape[1]):
# Writing column names
Table.Cell(1,col+1).Range.Text=str(df.columns[col])
for row in range(df.shape[0]):
# writing each value of data frame
Table.Cell(row+1+1,col+1).Range.Text=str(df.iloc[row,col])
I however get the following error:
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-32-b3ea6c24ddfe> in <module>
1 # data frame
----> 2 wordApp = win32.gencache.EnsureDispatch('Word.Application')
3 wordApp.Visible = False
4 doc = wordApp.Documents.Open(os.getcwd()+'\\template.docx')
5 rng = doc.Bookmarks("PUTTABLEHERE").Range
AttributeError: module 'win32' has no attribute 'gencache'
What am I doing wrong?

Error: module 'MSGARCH' has no attribute 'predict'

I am using the package rpy2 to use R language in Python environment. I am using the MSGARCH package which is only on R. The package is clearly suppose to come with the attribute predict.
https://rdrr.io/cran/MSGARCH/man/predict.html
I don't understand why I have this error. Do you have an idea please?
the full error message is :
Traceback (most recent call last):
File "markov.py", line 165, in <module>
pred = ms.predict(object = fitMCMC, newdata = None, nahead = '30L')
AttributeError: module 'MSGARCH' has no attribute 'predict'
The code is:
ms = importr('MSGARCH')
from rpy2.robjects import r, pandas2ri, numpy2ri, vectors
pandas2ri.activate()
numpy2ri.activate()
base = importr('base')
stats = importr('stats')
pred = ms.predict(object = fitMCMC, newdata = None, nahead = '30L')

'NoneType' object has no attribute 'fileno'

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from datetime import datetime
plt.style.use('ggplot')
columns = ['user_id','order_dt','order_products','order_amount']
df = pd.read_csv('CDNOW_master.txt',names = columns,sep = '\s+')
df['order_date'] = pd.to_datetime(df.order_dt,format='%Y%m%d')
df['month'] = df.order_date.values.astype('datetime64[M]')
f = df.groupby('user_id')['month'].min().value_counts()
print(f)
Above is my code,my purpose is to get the value_counts of the users purchased in their first month, but only got the result of 'NoneType' object has no attribute 'fileno'.
any ideas? much appreciate
here are the traceback

size = os.get_terminal_size(sys.__stdout__.fileno())
AttributeError: 'NoneType' object has no attribute 'fileno'

I am seeing this as well.
>>> type(sys.__stdout__)
<class 'NoneType'>
I get NoneType when calling dunder stdout while I am using idle. I assume that pandas wants to determine how much to display in the results and is looking for the sys output information. In the documentation, it mentions what this is, but not how to reset it.
I did this:
sys.__stdout__ = sys.stdout
and it fixed the problem, but I have not idea if I caused problems down the line.

You may wish to try out the following.
df = pd.read_csv('CDNOW_master.txt',usecols = columns,sep = '\s+')
instead of
df = pd.read_csv('CDNOW_master.txt',names = columns,sep = '\s+')
This solved my problem. Hope it solves yours too.

AttributeError: 'QgsComposition' object has no attribute 'setMapCanvas'

I am trying to save map and its legends using QGis Map composer. I have already template .
Here is code in python.
layers =iface.legendInterface().layers()
canvas=iface.mapCanvas()
for layer in layers:
# myFile = r"C:\Users\craj\Downloads\GraduatedTheme.qpt"
myFile = r"C:\Users\craj\Downloads\GraduatedTheme.qpt"
myTemplateFile = file(myFile, 'rt')
myTemplateContent = myTemplateFile.read()
myTemplateFile.close()
myDocument = QDomDocument()
myDocument.setContent(myTemplateContent, False)
newcomp = iface.createNewComposer()
newcomp.composition().loadFromTemplate(myDocument)
newcomp.composition().refreshItems()
for a in iface.mapCanvas().layers():
iface.legendInterface().setLayerVisible(a, False)
iface.legendInterface().setLayerVisible(layer, True)
newcomp.composition().refreshItems()
map_item = newcomp.composition()
map_item.getComposerItemById('map')
map_item.setMapCanvas(canvas)
map_item.zoomToExtent(canvas.extent())
newcomp.composition().refreshItems()
legend_item = newcomp.composition().getComposerItemById('legend')
legend_item.updateLegend()
newcomp.composition().refreshItems()
imagePath ='C:/Users/craj/Downloads/'+layer.name()+'.png'
image = newcomp.composition().printPageAsRaster(0)
image.save(imagePath,'png')
An error has occurred while executing Python code:
AttributeError: 'QgsComposition' object has no attribute 'setMapCanvas'
Traceback (most recent call last):
File "C:/Users/craj/.qgis2/python/plugins\JoinAttribute\Join_Attribute.py", line 436, in run
map_item.setMapCanvas(canvas)
AttributeError: 'QgsComposition' object has no attribute 'setMapCanvas'

If you look at the docs there is no setMapCanvas on QgsComposition. This method is in several other classes, such as QgsComposerMap. So based on the code calling getComposerItemById() what you likely need is this:
composition = newcomp.composition()
map_item = composition.getComposerItemById('map')
map_item.setMapCanvas(canvas)
