Huffman is a data compression algorithm. It is use for lossless data compression. Huffman tree is generated from text character’s frequencies and provides codes for each character. Sometimes while working on huffman tree you will get the error modulenotfounderror: no module named huffman. If you are getting this then in this entire tutorial you will know how to solve this issue easily.
The root cause of the error modulenotfounderror: no module named huffman
The main reason you are getting the modulenotfounderror: no module named huffman error is that you have not installed the Huffman module for the python. There is a python module huffman, which is not install in your system.
If you try to import the huffman in pycharm then you will see the dotted underline below the word huffman. It clearly indicates that the huffman package is missing and you will get the error no module named huffman.
The same case is for terminal or commands prompt if you try to import there then you will get the same message no module named huffman.
modulenotfounderror: no module named huffman Solution
The solution for this no module named huffman is very simple. You have to install the huffman python pakcage in your system. For this, you have to use the pip command.
Before that, you have to also check the version of the python in your system. If your system has python 3. xx version then you will use the pip3 command and if the system has python 2. xx then use the pip command.
Use the below command to check the version of the python.
The version of python in my system is 3. xx, therefore I will use the pip3 command.
Open your terminal and type the below command to install the huffman python package. Now you will not get the modulenotfounderror: no module named huffman error.
pip3 install huffman
Huffman is widely use for compressing data without losing data. It has many algorithms for compressing data. If you are getting the error no module named huffman then the above method will solve your the error.
