Thenp.array()function creates a numpy array namednum_val. Look in the output; its type isnumpy.ndarray. If you need more information about numpy array, visit this tutorialPython NumPy Array. Converting Tensor to Numpy in TensorFlow Now you know about tensor and numpy arrays. Let’s see how...
``I have a KerasTensor object with shape (None, 128, 128, 1) that I need to pass to an OpenCV function. However, I'm having trouble converting the KerasTensor to either a numpy array or a TensorFlow EagerTensor that can be accepted by the function. Specifically, I want to convert th...
跑tensorflow代码的时候遇到报错: NotImplementedError: Cannot convert a symbolic Tensor (ExpandDims:0) to a numpy array. This error may indicate that you're trying to pass a Tensor to a NumPy call, which is not supported 原代码: fromsklearn.metricsimportr2_score ... model.compile(optimizer='a...
