我已经训练了一个UBM模型,现在我正试图在我得到跟随错误时实现扬声器适应。
例外:show enroll / something.wav不在HDF5文件中
我在“feat”文件下面有两个文件“enroll”和“test”,它们分别包含用于训练和测试的功能(.h5),而我的enroll_idmap是用音频(.wav)生成的,仅用于训练。而且,我的wav文件和专家文件是分开的。我想我遇到了idmap的问题。 “enroll / something.wav”是我的enroll_idmap的右边,但那个“HDF5文件”是指什么?
谁能告诉我这个错误意味着什么以及如何解决它?
这是我的enroll_idmap的代码
def __init__(self):
BASE_DIR = "./Database/sidekit_data"
self.AUDIO_DIR = os.path.join(BASE_DIR, "audio")
self.FEATURE_DIR = os.path.join(BASE_DIR, "feat")
self.TASK_DIR = os.path.join(BASE_DIR, "task")
def create_idMap(self, group):
# Make enrollment (IdMap) file list
group_dir = os.path.join(self.AUDIO_DIR, group) # enrollment data directory
group_files = os.listdir(group_dir)
group_models = [files.split('_')[0] for files in group_files] # list of model IDs
group_segments = [group+"/"+f for f in group_files]
# Generate IdMap
group_idmap = sidekit.IdMap()
group_idmap.leftids = np.asarray(group_models)
group_idmap.rightids = np.asarray(group_segments)
group_idmap.start = np.empty(group_idmap.rightids.shape, '|O')
group_idmap.stop = np.empty(group_idmap.rightids.shape, '|O')
if group_idmap.validate():
group_idmap.write(os.path.join(self.TASK_DIR, group+'_idmap.h5'))
else:
raise RuntimeError('Problems with creating idMap file')
然后我得到enroll_idmap和test_idmap:
create_idMap("enroll")
create_idMap("test")
这是扬声器适配的代码,上面的错误在159_regat.accumulate_stat(...)的执行过程中出现:
BASE_DIR = "./Database/sidekit_data"
enroll_idmap = sidekit.IdMap.read(os.path.join(BASE_DIR, "task", "enroll_idmap.h5"))
ubm = sidekit.Mixture()
model_name = "ubm_{}.h5".format(NUM_GUASSIANS)
ubm.read(os.path.join(BASE_DIR, "ubm", model_name))
server_eval = sidekit.FeaturesServer(feature_filename_structure="./Database/sidekit_data/feat/{}.h5",
...
...)
print("Compute the sufficient statistics")
enroll_stat.accumulate_stat(ubm=ubm,
feature_server=server_eval,
seg_indices=range(enroll_stat.segset.shape[0]),
num_thread=nbThread
)
这似乎不是一个大问题,但它让我停了几天,请帮助。
我终于通过改变训练和测试功能的路径来解决这个问题,使其在“BASEDIR”之外
server_eval = sidekit.FeaturesServer(feature_filename_structure="./enroll/{}.h5",
...)
