How to pip install "lru"?

Question

I am trying to use a python deep learning module keras-audio to train from audio files (python 3.8.6, MacOS 10.14.6). However, after installing that module and trying to run an example I get the following error

Traceback (most recent call last):
  File "demo/cifar10_train.py", line 1, in <module>
    from keras_audio.library.cifar10 import Cifar10AudioClassifier
  File "/Users/user/keras-audio/keras-audio/keras_audio/library/cifar10.py", line 2, in <module>
    from lru import LRU
ModuleNotFoundError: No module named 'lru'

so I tried to install that package with

pip install lru

which created the following error:

Collecting lru

Any idea how to fix this error?

`raise KeyError, key` is Python 2 syntax, so it looks like this package hasn't been upgraded to work with Python 3. — snakecharmerb, Jan 24 '21 at 09:06
As @snakecharmerb, pointed this is python2 syntax. But in any case, I don't think they use that package. Looking at the [requirements.txt](https://github.com/chen0040/keras-audio/blob/c34c30695169e0f274c0f3d175dba2b4c9dc301a/requirements.txt#L9) it is [lru_dict package](https://pypi.org/project/lru-dict/) being used, but not mentioned in [setup.py](https://github.com/chen0040/keras-audio/blob/master/setup.py) — buran, Jan 24 '21 at 09:09
Yes thanks, looks like that. But then I get another error. I guess this is a dead end. There is no useful machine learning package. I need to write one! — Alex, Jan 24 '21 at 09:14
You may want to edit your post, then, because as written, the answer is `pip install lru-dict` — OneCricketeer, Jan 24 '21 at 10:56
Try `pip install libpython3.8-dev` and then install `pip install lru-dict` — Yashashvi, Jul 29 '21 at 14:42

Was getting the same issue, after installing pip install libpython3.8-dev it was fixed. For different version of python install package accordingly, i.e. pip install libpython3.6-dev

For different operation system, refer to this answer
