安装

Xiaochengzi · March 26, 2021, 7:12am

请教一下，这个安装后续需要用到互联网吗？我可以安装在我这边的内网中吗？

Xiaochengzi · March 26, 2021, 7:18am

我这个是VMcenter里面的虚拟机，可以运行吗？应该是属于没有独立显卡的那种

你好！安装GPU版本的MXnet过程中报错：
Building wheel for numpy (setup.py) … error
请问是什么原因？Python为3.8版本，CUDA退回10.2版本，
用pip install mxnet-cu102==1.7.0 -f https://dist.mxnet.io/python安装无法成功

EwingAdam · April 29, 2021, 8:32am

解决了，应该是因为Python版本太高，从3.8回退至3.6后安装没问题了。

按照安装步骤完成了但是出现两个问题。
OS：ubuntu-20.04.1
python3.8 | Miniconda3 Linux 64-bit

1.conda activate d2l后，python中
No module named ‘mxnet’.

2.运行jupyter notebook
jupyter command ‘jupyter-notebook’ not found.

请高手赐教。

foxfish · July 14, 2021, 11:43am

以上问题是GPU安装时出现的。
又按照CPU的放发安装了一次，运行jupyter notebook成功。

问题如下：

python3.6 | Miniconda3-4.3.31-Linux-x86_64.sh

1.conda activate d2l后，python中import mxnet
lllegal instruction （core dumped）

请教高手，谢谢。

foxfish · July 15, 2021, 2:47am

OS：ubuntu-20.04.1
python3.8 | Miniconda3 Linux 64-bit

第二个问题解决了，运行了
pip install -U d2l

第一个问题发生了变化
1.conda activate d2l后，python中import mxnet
lllegal instruction （core dumped）

GitHub980709 · July 15, 2021, 8:02am

请问一下，安装了mxnet过后，import的时候出现module ‘numpy’ has no attribute ‘histogram_bin_edges’，我把mxnet卸载了又安装，还是不行呢

在Win10上安装了基于CPU的环境，可以成功运行。大致步骤：

先安装miniconda -https://docs.conda.io/en/latest/miniconda.html ，我选的是python3.8
激活base环境 -cmdline窗口使用命令conda activate base
到pytorch主页（Start Locally | PyTorch ），获取安装pytorch的命令，我的大概是：conda install pytorch torchvision torchaudio cpuonly -c pytorch

如果安装中遇到如下错误：

RemoveError: 'requests' is a dependency of conda and cannot be removed from
conda's operating environment.

请使用如下命令更新：conda update --force conda
然后再尝试安装pytorch
4. 然后安装jupyter 和d2l包，在base 环境下，输入pip install jupyter d2l

5. 下载教程的jupyter记事本，就在教材页面右上方工具栏中（《动手学深度学习》 — 动手学深度学习 2.0.0 documentation ）

找个合适的目录解压缩

在base环境下启动jupyter notebook
一切正常，浏览器自动弹出，即可打开各章节jupyter notebook进行学习和试验了。
（注：由于是本地CPU版本，很多模型训练很慢，甚至是训练不出来）

麻烦看看如下的问题，安装之后遇到RuntimeError，在浏览器出现了ImportError，如下图，求解答，谢谢。

你好，我按照你的步骤进行了安装，安装的时候一切正常。但是到了激活环境的时候，就不行了
报错如下
输入：conda activate d2l
报错：Could not find conda environment: d2l
You can list all discoverable environments with conda info --envs.
请问您有遇到这样的问题吗？

zppet · August 10, 2021, 2:33am

d2l是咱们教程用的Python 包，而不是conda虚拟环境。你需要激活的是base虚拟环境，命令是：conda activate base

fff · August 10, 2021, 5:46am

非常感谢，现在activate base和deactivate都正常了。
但是我在打开jupyter notebook里的项目例子时，
报错：

错误码404一般表示服务端资源不存在。看样子你是不是没有把下载的jupyter notebooks解压？
我的是解压zip到我的windows用户目录，如图

我也是请问你后来解决了嘛？我是win10系统不知道你是什么系统……

请问如果不是Nvidia显卡就不能下载GPU嘛？我是AMD显卡怎么办，没有GPU有什么影响吗

YingLi · December 29, 2021, 4:04pm

正式版，支持CUDA的，好像是只到1.7.0，更高版本只有CPU版本。
而且D2L这个项目，是基于1.7.0 的。
