How to install wheel packages

Question

I am trying to install PocketSphinx in Python. I am trying to follow the Uberi speech recognition README, which asks the following:

PyAudio wheel packages for common 64-bit Python versions on Windows and Linux are included for convenience, under the third-party/ directory in the repository root. To install, simply run pip install wheel followed by pip install ./third-party/WHEEL_FILENAME (replace pip with pip3 if using Python 3) in the repository root directory.

I do not understand the instruction here. What FILE_NAME is this referring to? What is this wheel and how does it relate to PocketSphinx?

Answer 1

When you downloaded the PocketSphinx package manually, it must have created a wheel file (the file which does the real job) with a .whl extension in the said directory.

Now, you need to open a terminal in the directory where the .whl extension file is stored, which in this case is third-party.

Once you make sure that the terminal shows the current directory as third-party, go ahead and do a pip install of the wheel file.

Assuming the name of the wheel file to be PocketSphinx.whl,

You'd write:

pip install PocketSphinx.whl

This will do your job if all requirements are met.

And I have a feeling that the name of the wheel file wouldn't be simply PocketSphinx.whl, it'll be long and informative, nonetheless it will always have the extension .whl, by which you shall identify it.

Edit:

I went to the link you provided, and this is the wheel file you need:

pocketsphinx-0.1.3-cp35-cp35m-win_amd64.whl for python 3.5

Or

pocketsphinx-0.1.3-cp27-cp27m-win_amd64.whl for python 2.7

So your command becomes

pip install pocketsphinx-0.1.3-cp35-cp35m-win_amd64.whl

Or

pip install pocketsphinx-0.1.3-cp27-cp27m-win_amd64.whl

As per your python version.

Answer 2

What FILE_NAME is this referring to?

Filename of the binary package file in third-party folder of the repository. For example pocketsphinx-0.0.9-cp27-none-win_amd64.whl. You are supposed to checkout repository first.

What is this 'wheel' and how does it relate to pocketsphix?

wheel is a python package manager to install binary packages. It is used to install python binary package. You can read more here: https://pypi.python.org/pypi/wheel
