初始化 pytorch RPC 时 getBar1SizeOfGpu 出现运行时错误

标签：python pytorch rpc

我在系统上使用 PyTorch 和 RPC 后端时遇到运行时错误。错误信息如下：谁能告诉我为什么会出现这个问题以及如何解决它？谢谢。

我的代码是这样的

import os

import torch.distributed.rpc as rpc
from torch.distributed.rpc import BackendType
ompi_world_size = int(os.getenv('OMPI_COMM_WORLD_SIZE', 0))
ompi_world_rank = int(os.getenv('OMPI_COMM_WORLD_RANK', 0))

def recv_tensor(tensors,from_rank):
    print(f"Received tensors: {tensors} from rank {from_rank}")

if __name__ == '__main__':
    print(f"world_size: {ompi_world_size}, world_rank: {ompi_world_rank}")

    options = rpc.TensorPipeRpcBackendOptions(
        num_worker_threads=16,
        #device_maps={f"worker_{i}": {0: 0} for i in range(ompi_world_size)},
        init_method=f"file:///work/personal_workspace/data/sharedfile_rpc",
        rpc_timeout=30,
    )
    rpc.init_rpc(name= f"worker_{ompi_world_rank}", backend=BackendType.TENSORPIPE,
                rank=ompi_world_rank, world_size= ompi_world_size,
                rpc_backend_options=options)
    if rpc.is_available():
        print(f"RPC is available from rank {ompi_world_rank}")
    
    tensor = torch.ones(ompi_world_rank)
    rpc.rpc_sync("worker_0", recv_tensor, args=(tensor,ompi_world_rank))

    rpc.shutdown()

Chatgpt告诉我更新我的pytorch，我这样做了，但是没有用。

我使用的系统是由管理员管理的，我所能做的就是修改Python虚拟环境或加载不同版本的cuda。

The error message "RuntimeError: In getBar1SizeOfGpu at tensorpipe/channel/cuda_gdr/context_impl.cc:242 "": No such file or directory" suggests that there is an issue with the CUDA GDR (GPU Direct RDMA) component of the TensorPipe backend in PyTorch.

This issue might be caused by one of the following reasons:

1. Missing CUDA GDR Support:

Your system or CUDA installation might not have the necessary libraries or drivers for CUDA GDR.
Solution: Verify that your system and CUDA version support CUDA GDR. Check the NVIDIA documentation and your system's hardware specifications.

2. Incompatible CUDA Versions:

There might be a mismatch between the CUDA version used to build PyTorch and the one available in your environment.
Solution:
- Ensure that the CUDA version used to build PyTorch is compatible with your system's CUDA driver.
- You can rebuild PyTorch from source using the appropriate CUDA version or try a different PyTorch installation built with a compatible CUDA version.

3. Incorrect Library Paths:

The required CUDA GDR libraries might not be in the system's library path.
Solution:
- Verify that the directory containing the CUDA GDR libraries is included in your LD_LIBRARY_PATH environment variable.
- For example, you can add the following line to your shell configuration file (e.g., .bashrc ): bash export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
- Replace /usr/local/cuda/lib64 with the actual path to your CUDA library directory.

4. File System Permissions:

Insufficient file system permissions might be preventing access to the CUDA GDR libraries.
Solution:
- Check the permissions on the CUDA GDR library files and ensure that the user running the PyTorch script has read access to them.

Since you mentioned limited access to the system, try the following:

Contact your system administrator: Inform them about the issue and provide the error message. They might be able to install the necessary CUDA GDR components or resolve any system-level configurations.
Request a different PyTorch environment: If possible, request your administrator to provide a PyTorch environment built with a compatible CUDA version and with proper CUDA GDR support.
Consider alternative backends: If CUDA GDR is not feasible, explore using other PyTorch RPC backends, such as Gloo or MPI, which might not require CUDA GDR and could be easier to configure in your environment.
