numpy.core._exceptions.MemoryError：无法为形状为 (1073741824, 0) 且数据类型为 float32 的数组分配 0 个字节

Question

我正在尝试训练StyleGAN2 ，但每次我开始训练时都会遇到此错误。 奇怪的是它不能分配 0 字节。

这是一个麻木的错误还是我做错了什么？ 如果您能帮助我，我将不胜感激

这也在https://github.com/numpy/numpy/issues/16410 中报告，并在 https://github.com/numpy/numpy/pull/21477中修复，这可能包含在 numpy 版本 1.23 中。
