I've installed the module pyaudio using `pip`. However, when I try to import it, Python says the module is not found:

```
C:\Users\hp>pip install pyaudio
Requirement already satisfied: pyaudio in c:\users\hp\appdata\local\programs\python\python37\lib\site-packages (0.2.11)

```

```
>>> import pyaudio
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pyaudio'

```

Why can't Python find the installed module?

(I am using Python 3.7.)
