这个错误提示说明你的计算机内存不足,无法为一个形状为 (1181733, 5546) 的 float32 类型数组分配 24.4 GiB 的内存空间。可能的解决方法包括:
1. 减少数组的大小或数据类型,以减少内存占用。
2. 使用更高容量的计算机或服务器,以满足内存需求。
3. 使用分布式计算技术,将计算任务分布到多台计算机上进行并行计算,以减少单台计算机的内存压力。
4. 优化算法和代码,尽可能减少内存占用。

Unable to allocate 24.4 GiB for an array with shape (1181733, 5546) and data type float32
这个错误通常是由于你尝试在内存中分配一个太大的数组导致的。有几种方法可以解决这个问题:
1. 尝试使用更小的数组或使用更小的数据类型。例如,使用float16或int16类型而不是float32。
2. 如果你的计算机具有足够的内存,但仍然无法分配足够的内存,请检查您的操作系统和Python进程的内存限制设置。
3. 如果你的计算机没有足够的内存,你可以考虑使用分布式计算,或在云计算平台上使用更大的计算机实例。
希望这些方法能够帮助你解决问题!
MemoryError: Unable to allocate 25.2 GiB for an array with shape (58104, 58104) and data type float64
This error message occurs when the program tries to allocate more memory than the system can provide. In this case, the program is attempting to allocate 25.2 GiB of memory for an array with shape (58104, 58104) and data type float64, but the system does not have enough free memory to accommodate this request.
To resolve this error, you can try the following solutions:
1. Increase the available memory: If possible, try to free up some memory by closing other programs or processes that are running on the system. You can also consider upgrading the RAM on your computer to increase the available memory.
2. Use a more memory-efficient data type: If the data in the array does not require the precision of float64, you can consider using a lower precision data type, such as float32 or even int32 or int16, depending on the range of the data.
3. Use a sparse matrix: If the array contains mostly zeros, you can consider using a sparse matrix representation, which only stores the non-zero values and their indices. This can significantly reduce the memory requirements of the array.
4. Use a distributed computing framework: If the array is too large to fit in the memory of a single machine, you can consider using a distributed computing framework, such as Apache Spark or Dask, to distribute the computation across multiple machines.
