- Q: 安装过程
A1: 自己的方式
首先新建环境conda create -n fastaiV0
安装旧版本的pytorchconda install pytorch=0.3.1 -c pytorch
然后安装0.7版本的fastaipip install fastai==0.7.0 -i https://pypi.tuna.tsinghua.edu.cn/simple/
注意要将torchtext改为低版本的pip install torchtext==0.2.3
p.s. 因为我没有改源，所以用-i这种方式临时使用清华的源
A2: 官网的方式
首先下载它的整个文件夹，然后用conda create -f environment.yml完成环境创建
p.s.这种可能会下载一些自己暂时用不到的东西，此外本身没有安装fastai库，它借助每个课程目录下的fastai文件夹来import，所以局限在课程学习使用。
Q: read_feather() got an unexpected keyword argument 'nthreads'
A: 换库:import feather，然后用df_raw = feather.read_dataframe('tmp/bulldozers-raw')读取Q: failed to execute ['dot', '-Tsvg'], make sure the Graphviz executables …
A: 卸载原来pip安装的pip uninstall graphviz，用conda安装新版本conda install graphviz，发现还是没解决
于是brew install graphviz，很顺利，所以mac直接这样就行
也有可能是少安装了conda install -c conda-forge pydotplus，但我没试，非Mac的可以试下
- Q: ImportError: Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework. See the Python documentation for more information on installing Python as a framework on Mac OS X. Please either reinstall Python as a framework, or try one of the other backends. If you are using (Ana)Conda please install python.app and replace the use of 'python' with 'pythonw'. See 'Working with Matplotlib on OSX' in the Matplotlib FAQ for more information.
A: 在终端用vim之类的工具编辑~/.matplotlib/matplotlibrc，默认里面没有东西，然后增加一行backend: TkAgg并保存
-Q: AttributeError: module ‘torch’ has no attribute ‘float32’
A: 一开始的安装过程就说过了要 pip install torchtext==0.2.3
- LOG: 如果用官方的方式安装完想补充fastai本身，可能会报matplotlib版本的警告，所以建议用我的方式来安装
plotnine 0.5.1 has requirement matplotlib>=3.0.0, but you'll have matplotlib 2.2.3 which is incompatible.
