How to fix this error: ModuleNotFoundError: No module named 'notears'

[yaoyao22]

I want to run linear.py from the below website. But I always am stuck at line 90 of linear.py. How to fix the error? The linear.py code can be seen here: https://github.com/xunzheng/notears/blob.../linear.py

Traceback (most recent call last):
File "C:\Users\14047\notears\notears\linear.py", line 90, in <module>
from notears import utils
ModuleNotFoundError: No module named 'notears'

> Running a simple demo
The simplest way to try out NOTEARS is to run a simple example:

$ git clone https://github.com/xunzheng/notears.git
$ cd notears/
$ python notears/linear.py
This runs the l1-regularized NOTEARS on a randomly generated 20-node Erdos-Renyi graph with 100 samples. Within a few seconds, you should see output like this:

{'fdr': 0.0, 'tpr': 1.0, 'fpr': 0.0, 'shd': 0, 'nnz': 20}
The data, ground truth graph, and the estimate will be stored in X.csv, W_true.csv, and W_est.csv.

I want to fix the error. Then when I run linear.py, I can get the same output as authors suggest.

You do as described,need to have Git,and best to do this in a virtual environment.

I solve my problem. The original line 90 code is from notears import utils

I change it to import utils

Then the problem is solved. I get the output:
C:\Users\14047\notears>python notears/linear.py
{'fdr': 0.0, 'tpr': 0.95, 'fpr': 0.0, 'shd': 1, 'nnz': 19}
