Abstract: A model processing method and apparatus, a device, and a computer-readable storage medium. The method comprises: obtaining a first computational graph corresponding to a model to be trained and a parallelization strategy of said model, the parallelization strategy of said model comprising at least one of pipeline parallelism, model parallelism, data parallelism, and operator splitting (S601); adding parallelization information in the first computational graph according to the parallelization strategy of said model to obtain a second computational graph (S602); determining a distributed computational graph according to the second computational graph and computing resources (S603); and training said model according to the distributed computational graph (S604).

Abstract: A spectral analysis device is provided herein. The spectral analysis device includes a first lens, a transmission grating, a lens set and a sensing element. The first lens is configured to receive and converge an incident light beam into a first light beam. The transmission grating is configured to disperse the first light beam into a plurality of second light beams. The lens set is configured to receive the plurality of second light beams. The sensing element includes a substrate and a plurality of pixels. The plurality of pixels is configured to respectively receive the plurality of second light beam. Such structure is used to analyze the spectrum of incident light.
