Pytorch 2.0.1 failed to run a simple code which works on pytorch 1.13.0

import torch
import torch.distributed as dist
import time

# Code runs on each rank.
rank = dist.get_rank()
device = torch.device(rank)

world_size = dist.get_world_size()
datashape = world_size

input_data = torch.ones(datashape).to(device)
input_data *= rank
print(f"RAnk {rank} data: {input_data}")

if rank == 0:
    for i in range(1, world_size):
        dist.send(input_data, i)
        print(f"RAnk {rank} send data to rank {i}")
    dist.recv(input_data, 0)
    print(f"RAnk {rank} recv data from rank 0")
print(f"after broadcast on RAnk {rank} input data: {input_data}")

run the code above using this command:
torchrun --nnodes 1 --nproc_per_node 2 --standalone
On pytorch 1.13.0, it finishes with the correct result. However, on pytorch 2.0.1, it fails with this error:

master_addr is only used for static rdzv_backend and when rdzv_endpoint is not specified.

Setting OMP_NUM_THREADS environment variable for each process to be 1 in default, to avoid your system being overloaded, please further tune the variable for optimal performance in your application as needed.
