fast.ai(零)windows + pytorch 0.4
一、下载
git clone https://github.com/fastai/fastai.git
或者直接下载下来
二、安装pytorch
去官网安装建议安装即可
https://pytorch.org
如果下载失败,去这里
https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/win-64/
三、解决错误
教程中有import fastai 模块,不需要pip安装,源码中提供了,把 fastai 文件夹加入到路径下即可:
import sys sys.path.append('E:/fastai')
以 course/lesson1.ipynb 为例,cmd下运行
jupyter notebook E:\fastai
打开course/lesson1.ipynb,添加路径运行(粉色是加入你的fastai路径)
# Put these at the top of every notebook, to get automatic reloading and inline plotting %reload_ext autoreload %autoreload 2 %matplotlib inline import sys sys.path.append('E:/fastai')
然后往下运行,会出现各种库缺失,不要怕,缺啥pip安装就是了(下面是个例子)
No module named 'bcolz' -> pip install bcolz No module named 'graphviz' -> pip install graphviz No module named 'sklearn_pandas' -> pip install sklearn_pandas No module named 'isoweek' -> pip install isoweek No module named 'pandas_summary' -> pip install pandas_summary No module named 'tqdm' -> pip install tqdm No module named 'torchtext' -> pip install torchtext
然后运行 from fastai.transforms import * 还是会报错,解决方案参考这里
cd courses\dl1 del fastai mklink /d fastai ..\..\old\fastai cd ..\..
然后代码里涉及到路径的地方换成绝对路径就好了
