How to Solve Python AttributeError: ‘str’ object has no attribute ‘decode’
In Python 2, a string is an array of bytes, like bytes in Python 3. To get a Unicode string, you can call string.decode(). However, literal strings are Unicode by default in Python 3, and you do not need to decode them. If you try to decode a string in Python 3, you...
How to Solve Python ModuleNotFoundError: No module named ‘ConfigParser’
This error can occur if you are trying to import a package not supported by Python 3. In Python 3, ConfigParser has been renamed configparser, so any Python 2 packages using ConfigParser will throw the ModuleNotFoundError. To solve this error, you can use the Python 3...
How to Solve Python AttributeError: module ‘pandas’ has no attribute ‘rolling_mean’
In Pandas 0.18.0 and above, window functions like rolling_mean were refactored into methods on Series/DataFrame objects rather than top-level functions. The function rolling_mean is deprecated in Pandas version 0.18.0 and above. Instead of pd.rolling_mean(dataframe,...
How to Solve Python AttributeError: module ‘pandas’ has no attribute ‘dataframe’
DataFrame is an attribute of the pandas module. If you encounter this error, you have either misspelt DataFrame as dataframe, overridden the pandas import with a variable named pandas or pd, or you have a python script in your working directory called pandas.py or...
How to Solve Python AttributeError: ‘DataFrame’ object has no attribute ‘ix’
The Pandas method ix is deprecated as of version 0.20.0. If you want to index a DataFrame, you can use DataFrame.loc for positional indexing and DataFrame.iloc for label indexing. This tutorial will go through how to solve this error with code examples. Table of...
How to Solve Python AttributeError: ‘DataFrame’ object has no attribute ‘as_matrix’
The Pandas method as_matrix is deprecated as of version 0.23.0. If you want to convert a DataFrame to its NumPy array representation, you can use DataFrame.values() or DataFrame.to_numpy. This tutorial will go through how to solve this error with code examples. Table...
