I installed torch but got an error: No module named 'torch'

I installed torch v1.7.0

pip show torch

However, when I run

python mackey_glass_esn.py

I got the error

Traceback (most recent call last):
  File "mackey_glass_esn.py", line 24, in <module>
    import torch
ModuleNotFoundError: No module named 'torch'

Any ideas on what to do?

I run version 0.2.1 and then solved the problem. However, when I use version 0.2.3, the problem still exists.
