How to install the png module in python

Question

I'm kind of new to installing modules in python. I looked at this, http://pythonhosted.org/pypng/png.html#png.Reader.asRGB8 But there is no download link.

It says "installation is trivial" but trivial means of little value or importance. So I google "python png module download" but all the links are for 'pypng' It says to use import png not import pypng.

So then I google how to install python modules, And I came across easy install. But easy install has its own installation also.

Is my best bet to use c# or c++ instead where it's much easier to download libraries?

Answer 1

Try to print in command line/Terminal:

pip install pypng

and then import in your code as

import png

These are the same packages but it should be installed and be imported under different names

Answer 2

I encountered several errors while trying to install pypng . I solved it with running it as ROOT:

$ sudo pip install pypng

On Ubuntu 20.04 this works:

1. install pip

   sudo apt install python3-pip

2. install png

3. import library in code

   import png

Answer 4

对于 conda 用户，这是另一种选择：

conda install -c eaton-lab pypng
