You can access all of the underlying vectors in the model in a large numpy.memmap array of size (len(vectors) x vectors.emb_dim) like so:vectors.get_vectors_mmap()You can clean up all associated resources, open files, and database connections like so:vectors.close()...

(https://shtools.github.io/SHTOOLS/real-spherical-harmonics.html). To analyse the data and create the graphs and charts, we also used the following python packages: cartopy, matplotlib, netCDF4, numpy, pandas, string, and xarray. For the model weighting we used an implementation of ClimWIP...

The pixel-wise gradient magnitude similarity (GMS) is used to capture image local quality, and the standard deviation of the overall GMS map is computed as the final image quality index. 逐像素梯度幅度相似度(GMS)用于捕获图像局部质量,并计算整个GMS映射的标准偏差作为最终图像质量指标。我觉得和其他工...
