Segamation fault when using torch.profiler

:bug: Bug

when using the torch.profiler feature, it seems that cupti encouter a Segmentation fault problem in my enivorment.

To Reproduce

My code:

import math

import torch
import torch.nn.functional as F
import torch.optim as optim
from torchvision import datasets, transforms
import torchvision.models as models

train_dataset = \
    datasets.MNIST('./data', train=True, download=True,
                       transforms.Resize((224, 224)),
                       transforms.Lambda(lambda image: image.convert('RGB')),
                       transforms.Normalize(mean=[0.485, 0.456, 0.406],
                                 std=[0.229, 0.224, 0.225])


train_loader =, batch_size=1, num_workers=2)

# hyper parameter
epoch_ = 100
lr_ = 0.001
momentum_ = 0.9
milestones = [30, 80, 120]
log_interval = 10

model = models.alexnet(num_classes=10)
if torch.cuda.is_available():

optimizer = optim.SGD(model.parameters(), lr=lr_, momentum=momentum_)

scheduler = torch.optim.lr_scheduler.MultiStepLR(optimizer, milestones, gamma=0.1, last_epoch=-1)

with torch.profiler.profile(
    ) as p: 
    for epoch in range(0, epoch_):
        for step, (data, target) in enumerate(train_loader):
            if torch.cuda.is_available():
                data, target = data.cuda(), target.cuda()
            output = model(data)
            loss = F.cross_entropy(output, target)
            if step % log_interval == 0:
                print('Train Epoch: {} [{}/{} ({:.0f}%)]\tLoss: {:.6f}'.format(
                    epoch, step * len(data), len(train_loader),
                    100.0 * step / len(train_loader), loss.item()))
