I saw there is a way to directly read XML files using pandas. I followed and used this package. However, I keep getting errors.
https://pypi.org/project/pandas-read-xml/
import pandas as pd
import pandas_read_xml as pdx
from pandas.io.json import json_normalize
The error was generated by last line and the error is
ImportError: cannot import name 'json_normalize'
I am using kernel python 3, can anyone tell me what was wrong with it?

I want to open the .xlsx file through read_excel().
However, an error message is printed even though the openpyxl and pandas packages are installed.
The pandas version is 0.24.2 and the openpyxl version is 3.0.10.
The error message is - ValueError: Unknown engine: openpyxl
import pandas as pd
import math
retail_df = pd.read_excel('./Online_Retail.xlsx',engine='openpyxl')
print(retail_df.head())
In Pandas 0.24.2 the default engine is openpyxl and for that, you don't need to set it up manually during loading the excel file inside the read_excel() function.
So now your updated working code for reading excel files is :
import pandas as pd
import math
retail_df = pd.read_excel('./Online_Retail.xlsx')
print(retail_df.head())
Testing result from my side with this code.
I am currently learning python for data science, the problem I am running into is this
import pandas as pd
help(pd.read())
When I try to run this code it says 'AttributeError: module 'pandas' has no attribute 'read''
I am getting an error when I am going to read a VCF file using scikit-allel library inside a docker image and os ubuntu 18.04. It shows that
raise RuntimeError('VCF file is missing mandatory header line ("#CHROM...")')
RuntimeError: VCF file is missing mandatory header line ("#CHROM...")
But in the VCF file is well-formatted.
Here is my code of how I applied :
import pandas as pd
import os
import numpy as np
import allel
import tkinter as tk
from tkinter import filedialog
import matplotlib.pyplot as plt
from scipy.stats import norm
GenomeVariantsInput = allel.read_vcf('quartet_variants_annotated.vcf', samples=['ISDBM322015'],fields=[ 'variants/CHROM', 'variants/ID', 'variants/REF',
'variants/ALT','calldata/GT'])
version what Installed :
Python 3.6.9
Numpy 1.19.5
pandas 1.1.5
scikit-allel 1.3.5
You need to add a line like this in the first:
#CHROM POS ID REF ALT QUAL FILTER INFO FORMAT NA00001 NA00002 NA00003
but it's not static for all of the files, you have to make a Header like above for your file. (I suggest try this header first and if it's got error then customize it)
Whenever I try to run the following code I get an error message
import matplotlib
import pandas as pd
import _pickle as pickle
import numpy as np
print(matplotlib.version)
AttributeError: module 'matplotlib' has no attribute 'version'
I get the same error if i try this: matplotlib.style.use('bmh')
I'm using PyCharm
The errors are stating those attributes do not exist. It is not a problem of the installation.
To get the version:
print(matplotlib.__version__)
Regarding the style:
You do not "apply" that in matplotlib. You may want to use the module pyplot:
import matplotlib.pyplot as plt
plt.style.use("bmh")
I am trying to use Google colab for my project for which I have to upload a few python files because I need those class files.But while executing the main function.It is constantly throwing me an error 'module object has no attribute' . Is there some memory issue with colab or what! Help would be much appreciated.
import numpy as np
import time
import tensorflow as tf
import NN
import Option
import Log
import getData
import Quantize
AttributeError: 'module' object has no attribute 'NN'
I uploaded all files using following code :
from google.colab import files
src = list(files.upload().values())[0]
open('Option.py','wb').write(src)
import Option
But its always giving me error on some or the other files which I am importing.
The updated version (for a few weeks) can save the files without you having to call open(fname, 'wb').write(src)
So, you only have to upload your 5 files: NN.py, Option.py, Log.py, getData.py, and Quantize.py (and probably other dependency + data) then try importing each one e.g. import NN to see if there's any error.
