这个版本不兼容大家是怎么解决的呀，大家使用的 numpy，pandas，d2l, python 都是什么版本呀

pip install jupyter d2l  后报错，请问这个要怎么解决啊？

error: command ‘C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\cl.exe’ failed with exit code 2
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for pandas
Failed to build matplotlib numpy pandas

同样的问题，如何解决啊

纯净的环境也安装不上d2l，python3.9能装上，运行就报错。

各位别像我一样耍小聪明用 python 3.10， 当前 d2l包和相关依赖只支持Python 3.9

Python 的 版本装错了， 只能装 python 3.9，然后 pandas 的版本得退回到 1.2.4

参照文档，M2机器，在python3.9下，
pip install torch==1.12.0
pip install torchvision==0.13.0
pip install d2l==0.17.6

执行导入d2l包之后报错

同样报错，兄弟解决了嘛。。。。。。。。。。

@Bill_Jin @WYWY 解决了！使用pip install d2l==1.0.0b0

还在吗，我是这样弄好的
pip install d2l ——> pip install d2l pandas==1.5.3

运行代码jupyter notebook后显示，‘jupyter’ 不是内部或外部命令，也不是可运行的程序
或批处理文件。请问这里应该如何解决？

这个是用来把notebook编译成PDF文件时用的标签，具体代码在：https://github.com/d2l-ai/d2l-book/tree/master/d2lbook

Why is it that my CUDA is installed, but I can’t call it in my program. Entering nvcc -V in cmd displays the version number correctly, and the cuDNN files are configured according to the tutorial.

windows下推荐使用wsl：

下图说明可以用到gpu:

如果没有独立显卡，已安装conda或miniconda后，通过如下命令安装pytorch：

conda install pytorch torchvision torchaudio cpuonly -c pytorch

教大家一个非常简单安装d2l包的方法，首先去开源仓库【https://github.com/d2l-ai/d2l-zh/tree/master/d2l 】把里面的d2l文件夹下载到本地，然后把d2l文件夹移入你的pycharm项目里面，并且把d2l文件夹搞成pycharm的模块，后续使用【from d2l import torch as d2l】的时候就可以直接调用本地的d2l包了，这样也就没有安装不上的烦恼了。不过这种方法可能不适用于jupyter(没有验证过)

请问下载用CPU的mxnet时遇到这样的情况应该如何解决？

还想请问一下cuda版本12.0（？）有支持的mxnet版本吗？还是说需要downgradeCUDA的版本？

安装d2l 出错，错误内容似乎在register_finder(pkgutil.ImpImporter, find_on_path)，怎么解决呢？：
