Issues During Installation

Hi,

ESPnet is really an impressive toolkit, and I am trying to run the [`asr_library.ipynb` ](https://github.com/espnet/notebook/blob/master/asr_library.ipynb) on colab. However, during installation, I run into this problem:
```
tar: ./ubuntu16-featbin.tar.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
cp: cannot stat 'featbin/*': No such file or directory
```
Then when I try to run the `run.sh`, I got this problem:
```
steps/make_fbank_pitch.sh: [info]: no segments file exists: assuming wav.scp indexed by utterance.
run.pl: 8 / 8 failed, log is in exp/make_fbank/test/make_fbank_pitch_test.*.log
```

I also tried to use the installation code from this [tutorial](https://github.com/espnet/interspeech2019-tutorial/blob/master/notebooks/interspeech2019_asr/interspeech2019_asr.ipynb), then I can successfully run the `run.sh`. But I got this error ```ModuleNotFoundError: No module named 'espnet.utils.training'``` when I run ```from espnet.utils.training.batchfy import make_batchset```.

I would really appreciate if anyone could help me with these issues!
