安装./install/install-delta.sh nlp cpu报错

[Hejp5665]

SSLError(MaxRetryError('HTTPSConnectionPool(host='repo.anaconda.com', port=443): Max retries exceeded with url: /pkgs/main/noarch/repodata.json.bz2 (Caused by SSLError(SSLError("bad handshake: SysCallError(104, 'ECONNRESET')",),))',),)
这个怎么解决

[applenob]

这么看应该是安装时期的网络错误，建议重新安装下。

建议国内用户把安装脚本里面关于软件源的注释打开tools/install/install-delta.sh：

# If you are a user from mainland China, you can use following codes to speed up the installation.
# conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
# conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
# conda config --set show_channel_urls yes
# pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

如果还有问题麻烦提供下更完整的log。

嗯，谢谢你的回复，问题已经解决，现在又有了新的问题
我在运行 python3 delta/main.py --cmd train --config egs/conll2003/seq_label/v1/config/seq-label.yml
出现这样问题错误，请问这个是什么原因导致的

这个是自定义op编译的问题。现在tensorflow在用g++4.8编译custom op的时候偶尔会有这个bug。

可以使用conda install -c conda-forge cxx-compiler升级下当前conda环境的g++版本。

然后重新编译下custom op：

pushd delta/layers/ops/
./build.sh delta
popd
