1. 解释ValueError: zero-dimensional arrays cannot be concatenated错误的含义 ValueError: zero-dimensional arrays cannot be concatenated 这个错误通常发生在尝试使用NumPy的数组拼接函数(如numpy.concatenate、numpy.vstack、numpy.hstack等)
arr=np.array([1,2,3])# ⛔️ ValueError: zero-dimensional arrays cannot be concatenatednew_array=np.concatenate(arr) Thenumpy.concatenate()method joins a sequence of arrays along an existing axis. We only passed a single one-dimensional array to thenumpy.concatenate()method which caused the...
To avoid the ValueError, ensure that you are not attempting to concatenate zero-dimensional arrays. Conclusion TheValueError: Zero-dimensional arrays cannot be concatenatederror occurs when attempting to concatenate arrays that have zero dimensions. This error occurs due to the ill-defined nature of co...

(Fig.5a), binary dot arrays encoded by a standard computer file format were replicated into the raw glass (Supplementary Movie1). Points undergoing color change and those remaining unchanged represented binary codes “1” and “0”, respectively, generating binary data spelling out the “BNU” ...
A heterostructure of FBN quantum dots with a wide band gap semiconductor, titania nanotube arrays, exhibited high photocatalytic activity as evidenced by high external quantum efficiency extending from ultraviolet to green region of the solar spectrum (~24% at 400 nm). The high activity was ...
[44]. In 2013, it was reported that the interaction between MSCs and vertically aligned SiNW arrays on silicon substrates preferentially resulted in osteogenic and chondrogenic differentiation of MSCs, apart from the significant improvement in cell adhesion and proliferation [45]. Mechanical stimulation...
