如何比较yaml中几种备忘录的内容？

Question

我必须从yaml文件中检查以下几个条件：

provider: sockets
delayed_free_threads: 0
ATL_threads: 0
ATL_queue_size: 1000
ATL_data_size: 1024
Memservers:
  0:
    memory_type: volatile
    fam_path: /dev/shm/vol_path
    rpc_interface: fam5:8793
    libfabric_port: 7500
    if_device: eth0
  1:
    memory_type: volatile
    fam_path: /dev/shm/vol_path
    rpc_interface: fam4:8793
    libfabric_port: 7500
    if_device: eth1
  2:
    memory_type: volatile
    fam_path: /dev/shm/vol_path
    rpc_interface: fam3:8793
    libfabric_port: 7500
    if_device: eth1

下面是我要检查的条件:1.如果rpc_interface相同的话。2.如果rpc_interface是相同的，那么fam_path是一样的吗?3.如果rpc_interface是相同的，libabric_port是一样的吗？

下面是我尝试过的代码：

def compare():
    host_port = {}
    fam_path_list = {}
    libabric_port_list ={}
    file_in = Path(r'C:\Users\User\OneDrive\Desktop\toold\fam_memoryserver_config.yaml')
    yaml = ruamel.yaml.YAML(typ='safe')  
    data = yaml.load(file_in)
    print(data.values())
    for machine, config in data.values():
            if 'rpc_interface' not in config: 
                print(f'machine {machine} has no "rpc_interface"');
                sys.exit(1)
            else:
                host_port.setdefault(con['rpc_interface'], set()).add(machine)
                fam_path_list.setdefault(config['fam_path'], set()).add(machine)
                libabric_port_list.setdefault(config['libfabric_port'], set()).add(machine)
    # check if host_port has any values that have more than one machine
    for hp, machine_nrs in host_port.items():
        if len(machine_nrs) == 1:
            continue
        j=[str(x) for x in machine_nrs]
        print(f'Found {hp} in machines: {", ".join(j)}')
   
    for hp, machine_nrs in fam_path_list.items():
        if len(machine_nrs) == 1:
            continue
        k=[str(x) for x in machine_nrs]
        print(f'Found {hp} in machines: {", ".join(k)}')

    for hp, machine_nrs in libabric_port_list.items():
        if len(machine_nrs) == 1:
           continue
        l=[str(x) for x in machine_nrs]
        print(f'Found {hp} in machines: {", ".join([str(x) for x in machine_nrs])}')

    def removeElements(j, k):
        return ', '.join(map(str, j)) in ', '.join(map(str, k))

    if (removeElements(j, k)==True) :
        print(f'The memory servers {j}, have the same fam_path, hence Validation failed!')
    else:
        print('Only the rpc_interface of the machines are same, hence Validation failed!')
 

    def removeElements(j, l):
        return ', '.join(map(str, j)) in ', '.join(map(str, l))

    if (removeElements(j, l)==True) :
        print(f'The memory servers {j}, have the same libfabric_port, hence Validation failed!')
        
    else:
        print('Only the rpc_interface of the machines are same, hence Validation failed!')

compare()

但我所犯的错误是：

for machine, config in data.values():
ValueError: too many values to unpack (expected 2)

请告诉我怎么改正

您的data是一个dict (从YAML中的根级映射加载)。如果在data.values()上迭代，则只得到值，即sockets、0等。you不能将该值分配给两个变量。

由于您正在rpc_interface上进行测试，所以您可能希望这样做：

for machine, config in data['Memservers'].items():
