Answer 1

To fix the problem, I downloaded swig for windows

1. Copy swig.exe to the python installation folder (for ex C:/python27)

2. Open swigwin-3.0.12/Lib folder and copy all *.swg files to the C:/python27/lib or equivalent python path

3. Open swigwin-3.0.12/lib/python and copy all the files to (C:/python27/lib)

(Also make sure you have Microsoft Visual C++ Compiler for Python installed)

These steps worked for me.

Answer 2

You try to install pocketsphinx with pip, that will download and compile this module. It requires some compiling tool like swig.

Another solution is to install a binary version of pocketsphinx. You can download a binary version here. You have to select the correct version with respect to your installation.

To determine which one you have to download, you can run the following commands, that will tell you which version you require and whether you run a 32 or 64 bit python interpreter.

"C:\Users\krush\Anaconda3\python.exe" --version
"C:\Users\krush\Anaconda3\python.exe" -c "import struct;print(struct.calcsize('P') * 8)"

Below are some commands that you may enter once you have downloaded the correct version

"C:\Users\krush\Anaconda3\python.exe" -m pip install pocketsphinx‑0.1.3‑cp35‑cp35m‑win32.whl
"C:\Users\krush\Anaconda3\python.exe" -m pip install pocketsphinx‑0.1.3‑cp36‑cp36m‑win_amd64.whl

Answer 3

Instead of copying Swig files to the Python folder, you can simply add Swig`s location to the environment variables:

1. Press Ctrl+S
2. Type env and press Enter
3. Double click on Path
4. Add the path-to-Swig to the last blank line
5. Click OK and restart your PC

Answer 4

conda install swig
pip install pocketsphinx

I didn't want to do all that setup other people are suggesting so I tried this and it worked. This probably only works if you are using Anaconada though.

Answer 5

I was also getting same error, while installing in ubuntu 16.04, I executed following commands:

sudo apt-get install -y python python-dev python-pip build-essential swig git libpulse-dev

sudo pip install pocketsphinx

source: pocketsphinx-python

Answer 6

In case you are working on anaconda navigator.
Just go to environment.
Search swig, your package will be displayed. Select the package and click on apply button. It will also give a prompt list of other dependencies, which need to be installed with swig.
So just select all and click on apply button.
All the dependencies will be installed in your root directory of anaconda.

This worked for me, hope it helps.

Answer 7

There are few set of commands to resolve this. Just execute them:

sudo apt-get install -y python3 python3-dev python3-pip build-essential swig git libpulse-dev

sudo apt-get install libasound2-dev

sudo pip install pocketsphinx
