janelu9 opened a new issue #8065: Help? when I go on training a language model, errors occured URL: https://github.com/apache/incubator-mxnet/issues/8065 my model: ``` import mxnet as mx import numpy as np from word2vec_io import BucketSentenceIter import pickle as pk sym, arg_params, aux_params = mx.model.load_checkpoint('output/5_gram', 10) def Perplexity(label, pred): label = label.T.reshape((-1,)) loss = 0. for i in range(pred.shape[0]): loss += -np.log(max(1e-10, pred[i][int(label[i])])) return np.exp(loss / label.size) N=5 batch_size=64 data=pk.load(open('.//data//train.pkl','r')) data=[i[0] for i in data] data_val=pk.load(open('.//data//test.pkl','r')) data_val=[i[0] for i in data_val] train=BucketSentenceIter(data,batch_size,N) val=BucketSentenceIter(data_val,batch_size,N) devs = [mx.gpu(i) for i in range(1)] mod = mx.mod.Module(symbol=sym, context=devs) mod.fit(train, val, num_epoch=8, arg_params=arg_params, aux_params=aux_params, epoch_end_callback=mx.callback.do_checkpoint("./output/5_2gram"), eval_metric = mx.metric.np(Perplexity)) ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
