unyt: Manipulate and Convert Units in NumPy Arrays
Working with NumPy arrays that have units can be difficult, as it is not immediately clear what the units are, which can lead to errors.
The unyt package solves this by providing a subclass of NumPy’s ndarray class that knows units.
unyt arrays support standard NumPy array operations and functions while preserving the units associated with the data.

Check if Two NumPy Arrays Are Equal
If you try to check whether two arrays are equal, using an assert statement will give you an error. Use assert_array_equal instead.
assert_array_equal also shows you which elements are different between two arrays.

NumPy.testing.assert_almost_equal: Check If Two Arrays Are Equal up to a Certain Precision
Sometimes, you might only want to check if two arrays are equal up to a certain precision. If so, use np.testing.assert_almost_equal.
The code above shows an example of this method.

Numpy Comparison Operators
If you want to get elements of a Numpy array that are greater, smaller, or equal to a value or an array, simply use comparison operators such as <, <=, >, >=, ==.
The image above shows an example of using comparison operators.

np.all: Test Whether All Elements along a Given Axis of a NumPy Array Evaluate to True
If you want to test whether all elements along a given axis of a NumPy array evaluate to True, use np.all.
In the code above, I check if all elements are less than 3 in each column or row.
