tensor.dtype.to_complex() crashes kernel after ~100 calls in ipython kernel #124868
Description
🐛 Describe the bug
The following block of code consistently crashes an ipython kernel without an error traceback after ~100 iterations in the loop:
import torch
for i in range(1000):
d = torch.float32.to_complex()Running on torch==2.2.2+cu121, and I tried in on a couple google colab instance with torch==2.2.1+cu121 and torch==2.2.0+cpu with the same result.
It crashes with all real dtypes.
It does not crash in a terminal python kernel, but does sometimes cause a segmentation fault after the script ends.
For anyone looking for a workaround, you can just use this:
def dtype_to_complex(dtype: torch.dtype) -> torch.dtype:
"""
Converts a real torch dtype to a complex dtype. \n
RH 2024
Args:
dtype (torch.dtype):
Real dtype to convert to complex dtype.
Returns:
(torch.dtype):
complex_dtype (torch.dtype):
Complex dtype.
"""
map = {
torch.float16: torch.complex32,
torch.bfloat16: torch.complex64,
torch.float32: torch.complex64,
torch.float64: torch.complex128,
}
if dtype not in map:
raise ValueError(f'{dtype} does not have a complex equivalent in map.')
return map[dtype]
