Using thenumpy.asarray()method to convert list to matrix in Python. Similar to thenumpy.array()method mentioned above, thenumpy.asarray()method is utilized to convert different data type objects like lists, dictionaries, and more intoNumPymatrices. Thenumpy.asarray()basically calls thenumpy.arra...
To convert a Python list to a numpy array use either 1. numpy.array(), or 2. numpy.asarray(). The subtle difference is that numpy.array() will create a new array by default whereas numpy.asarray() will not create a new array by default.

If you are familiar with tensors, let’s see how to convert a list to a tensor. TensorFlow has a function calledtf.convert_to_tensor()that allows you to convert Python lists into tensors. Not only Python lists but also it can convert other objects or numpy arrays into tensors. ...
If a python list argument to np.array contains a mixture of int and np.uint64, the array will have dtype=np.float64. Which results in a loss of information, since values are not exactly representable by float64. Reproducing code example:...
