Loss: Nan #65

用的是SynthText数据集，训练时出现：

RankWarning: Polyfit may be poorly conditioned 
edge = fit_line([p0[0], p1[0]], [p0[1], p1[1]])

上面的警告不影响训练，训练一段时间后loss出现Nan值。我并没有执行build.sh这个程序，因为学校集群环境中没有NVCC。看其他问题中提到好像也不需要编译它。 希望问题能得到解决。

No, I'm looking at the code details of this project. You can add my WeChat and let's discuss it together.

Maybe CRNN's ctcloss function problem. You can use pytorch==1.1.0 and warp-ctc or refer to this link.

问题太久了,大概是因为ctc引起的问题,google一下ctc引起loss nan的问题,应该很好找到答案.这个项目我没有继续做下去,最终效果我也没有呈现.所以,我准备关闭问题了,也不要加我微信了,谢谢.
