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 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 first sub in Modin for Pandas for the benefit of distributed work over multiple cores:
import modin.pandas as pd
from modin.config import Engine
Engine.put("dask")
After initializing my dataframe, I attempt to use:
df['bins'] = pd.cut(df[column],300)
I get this error:
TypeError: ('Could not serialize object of type function.', '<function PandasDataframe._build_mapreduce_func.<locals>._map_reduce_func at 0x7fbe78580680>')
Would be glad to get help.
I can't seem to get Modin to perform the way that I want out of the box, the way I expected.
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?
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 doing some timeseries forecasting, while at it I am trying to import auto_arima using pyramid but it throws an Module not found error as - ''No module named 'pyramid.arima'
from pyramid.arima import auto_arima
I also tried importing auto_arima from pmdarima :
from pmdarima.arima import auto_arima
but this throws an error as -
"type object 'pmdarima.arima._arima.array' has no attribute 'reduce_cython'"
What am I doing wrong?...
I'm using pmdarima package without any issues, but your error is highly probably related to your numpy version. I would recommend to you to upgrade it (in case you use pip):
pip install --upgrade numpy
You can also try to import numpy package before importing auto_arima (some people experience strange behavior).
You can follow discussion on github issues - https://github.com/tgsmith61591/pmdarima/issues/91 (similar here or here). You're definitely not the first one with that issue.
If it doesn't help, please, paste your pmdarima and numpy versions.
