How to resolve conflicts between pycolmap and pytorch

[Lanqingsong]

I tested the simultaneous running of pycolmap and pytorch on multiple Windows devices and multiple versions. As long as the two packages are not imported at the same time, there will be no error. Once pycolmap and pytorch are imported at the same time, an error will be reported.
For example, the following code：
``
from time import time
from fastprogress import progress_bar

from collections import defaultdict
from copy import deepcopy
import concurrent.futures

import torch

import h5py
from copmap import CONFIG,reconstruct_from_db
if name == 'main':

a = 0

I tried installing pycolmap versions 0.4, 0.5, and 0.6 but none of them worked.

I meet the same mistake.Do you work it at Windows? maybe the windows is the reason why.Do you solved it?

problem solved, upgrade your PyTorch

I have never observed such behavior on Linux or MacOS and I don't have access to a Windows machine so it will be hard to debug this issue. First, I would suggest checking whether this still occurs with latest versions of PyTorch and with pycolmap built from source.
