modulenotfounderror: no module named huffman error occurs if we invoke huffman module in our python script and it is not installed properly. Actually, Huffman python module provides an interface to deal with data compression technique. Actually implementing huffman algorithm from scratch is quite a time consuming and a bit complex. Hence if we are coding in python then we can install the third parting python module Huffman and implement its complex logic via calling underline simple functions. But if we direct invoke the same while installation or if the path is causing the issue we get this error.
The best way to fix this error is to reinstall the package and then check the path for this. In the next section, we will explore the technique for installation.
modulenotfounderror: no module named huffman – Solution
The easiest way to install huffman python module is the pip.
Solution 1: Huffman with pip ( Install ) –
Use the below command.
pip install huffman
Currently, at the time of writing this article, There are two versions of Huffman. The above command will install the latest version out of it. In order to be version specific with huffman, we can provide the version along with it.
pip install huffman==0.1.0
Solution 2: Python setup for huffman –
If the error is due to a path setup issue. Actually installation of any python package itself setup the path in sys.path of the python interpreter. But in some cases due to unusual failure, the Interpreter is not able to resolve the path. In those situations we need to append the path manually in sys.path. We can add it dynamically in the current python script by adding the below line.
sys.path.append('Put here huffman path')
If the dynamic path setting is working fine then you can uninstall the huffman and reinstall it. It will setup the path implicitly. Or you can continue with the dynamic mode itself. The only drawback for dynamic path addition is we have to repeat it with each script where we import huffman module.
You may try the below command with conda manager as an alternative of huffman.
conda install -c auto huffman-encoder-decoder
