How can I debug a failed hidden test for code project?
I am trying to complete the Data Science 8 Code project: Average of Rows. It completes all tests except the last one which is hidden. How can i find out why it's failing the final test? I thought it may be because the last test output was int instead of float, but I added an if statement that should of resolved that and it still fails the last test. https://code.sololearn.com/cdJ85oIgBOu0/?ref=app

Review the operations section of the course that preceeded this module project. Pay attention to the yellow boxes and some of the available methods of a numpy array. Reread the task as it gives you a hint as to what method needs to be used in the description.
Build the passed in matrix as a list then convert that list to a numpy array. Loop over each row and find its "average", using the aforementioned method, rounding to 2 decimal places, and add each rows average to a list. Then convert this list to a numpy array and output it.

using the mean method solved the issue. I guess the method has some difference in precision that effected the round function slightly.

Pls provide project description

In a matrix, or 2-d array X, the averages (or means) of the elements of rows is called row means.
Task
Given a 2D array, return the rowmeans.
Input Format
First line: two integers separated by spaces, the first indicates the rows of matrix X (n) and the second indicates the columns of X (p)
Next n lines: values of the row in X
Output Format
An numpy 1d array of values rounded to the second decimal.
