这一篇将会介绍卷积神经网络 (CNN),CNN 模型非常适合用来进行图片相关的学习,例如图片分类和验证码识别,也可以配合其他模型实现 OCR。 使用Python 处理图片 在具体介绍 CNN 之前,我们先来看看怎样使用 Python 处理图片。Python 处理图片最主要使用的类库是 Pillow (Python2 PIL 的 fork),使用以下命令即可安装: pip3 ...
运行代码: python main.py 另外此代码加了tensorboard,将在工程目录下生成 xxx_log 的文件。 然后使用:tensorboard --logdir arch_inceion_v4_rnn_log查看。 后续有时间会把其它的功能加上。 其中,z_ckpt_pb:ckpt转pb的代码,和测试接口。 对dl感兴趣,还可以关注我的博客,这是我的博客目录:(地址:http://blo...
A basic understanding of Python code and Neural Networks is needed to follow along with this tutorial, along with a familiarity with the PyTorch framework. We recommend this article to intermediate to advanced coders with experience developing using PyTorch. ...
