I did !pip install tree on google colab notebook. It showed that Pillow in /usr/local/lib/python3.6/dist-packages (from tree) (4.3.0). But when I use !tree. The notebook reminded me that bin/bash: tree: command not found. How to solve it?

I tried several times but all failed.

It showed:

!pip install tree
!tree

I expect it shows the structure of the files in the directory.

You seem to have confused pip with the local package manager?

!apt-get install tree does what you want:

.
└── sample_data
    ├── anscombe.json
    ├── california_housing_test.csv
    ├── california_housing_train.csv
    ├── mnist_test.csv
    ├── mnist_train_small.csv
    └── README.md

1 directory, 6 files

I think you have installed wrong tree with pip https://pypi.org/project/Tree/

Right code for install on Mac brew install tree

sudo apt-get install tree

the command for Debian / Ubuntu Linux / Mint sudo apt install tree

Any request feel free for contact

also, it's doesn't work for me but here is an alternative code for the tree dictionary

import os
for path, dirs, files in os.walk('/content/sample_data'):
  print (path)
  for f in files:
    print (f)
