我正在制作一个通过 Surface EMG 信号进行手语识别的项目。现在，我想通过一个名为“single”的数组来训练一个 GMMHMM 模型。它的形状是 (2520, 840)。

for single in Norm_Feat_Vsplit:
    # print(shape(single))  # (180, 840)
    # print(type(single))  # <class 'numpy.ndarray'>
    clf = hmm.GMMHMM(n_components=7, n_mix=4, covariance_type="diag", n_iter=10)
    print('Training ' + str(index) + ' model... ')
    clf1 = clf.fit(single)
    print('Training finished!')
    # Save model
    print('Saving model...')
    joblib.dump(clf1, "Hmm_model" + str(index) + ".m")
    print('Saving finished!')

但是总会有一个ValueError如下：（有时它似乎能够成功训练第一个GMMHMM模型，但第二个会出错。）输出：

Training 1 model... 
Traceback (most recent call last):
  File "E:/桌面/手语识别资料/程序/Single_Hand/Single_Hand/One_Hand_Train(注释).py", line 378, in <module>

    clf1 = clf.fit(single)

    bwdlattice)
  File "D:\Anaconda3\lib\site-packages\hmmlearn\hmm.py", line 607, in _accumulate_sufficient_statistics
    raise ValueError

感谢您的帮助！
