mxnet使用mxboard可视化模型权重参数报错：No handlers could be found for logger “mxboard.event_file_writer“

No handlers could be found for logger “mxboard.event_file_writer”

解决：

$ pip install tensorboard

在代码中加入：

import logging
logging.basicConfig(level=logging.DEBUG)

训练过程中的可视化

    # visualize
    from mxboard import SummaryWriter
    import logging
    logging.basicConfig(level=logging.DEBUG)
    sw = SummaryWriter(logdir='./logs', flush_secs=5)
    net = mfc1
    argp,auxp = net.get_params()
    grads = [i for i in argp.values()]

    param_names = argp.keys()
    assert len(grads) == len(param_names)
    # logging the gradients of parameters for checking convergence
    for i, name in enumerate(param_names):
        sw.add_histogram(tag=name, values=grads[i], global_step=0, bins=10)
