failed to interpret .midi file as a pickle

wanshun123 commented 5 years ago

When trying to train like the following:

python main.py --dataset_A_dir='Classic' --dataset_B_dir='Jazz' --type='cyclegan' --model='full' --sigma_d=1 --phase='train'

The code fails where it tries to load a .midi file as a numpy array in the load_npy_data() function (added print statements):

def load_npy_data(npy_data):
    print('printing npy_data for the load_npy_data function...') 
    print(npy_data)
    npy_A = np.load(npy_data[0]) * 1.
    npy_B = np.load(npy_data[1]) * 1.
    npy_AB = np.concatenate((npy_A.reshape(npy_A.shape[0], npy_A.shape[1], 1),
                             npy_B.reshape(npy_B.shape[0], npy_B.shape[1], 1)), axis=2)
    return npy_AB

As follows:

I think the problem is the datasets you feed. Please take a look at datasets part in ReadMe.

我认为问题在于您提供的数据集。请查看自述文件中的数据集部分。

Hello, I think the convert used in the second step of data preprocessing_ There is a problem with the converter function in clean.py. It cannot implement the function when installing the package you specified
