1.问题
Could not load dynamic library 'libcudart.so.11.0';
dlerror: libcudart.so.11.0: cannot open shared object file: No such file or directory;
LD_LIBRARY_PATH: /usr/local/cuda-10.0/lib64:
https://blog.csdn.net/qq_26018075/article/details/111546689,需要安装:
conda install cudatoolkit=11.0
最终原因是,tensorflow是2.4版本,但已有的cuda版本为10.1,所以需要将tf降级。
但尝试安装卸载都出现问题,尝试使用conda和pip来卸载都不行:
conda uninstall tensorflow #报错: Collecting package metadata (repodata.json): failed CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/linux-64/repodata.json> Elapsed: - An HTTP error occurred when trying to retrieve this URL. HTTP errors are often intermittent, and a simple retry will get you on your way. 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/linux-64'
#尝试: pip uninstall tensorflow WARNING: Skipping tensorflow as it is not installed.
尝试使用两者直接安装新版本也不行:
pip install tensorflow==2.0.0 #报错: ERROR: Could not find a version that satisfies the requirement tensorflow==2.0.0
(from versions: 2.2.0rc1, 2.2.0rc2, 2.2.0rc3, 2.2.0rc4, 2.2.0, 2.2.1, 2.2.2, 2.3.0rc0, 2.3.0rc1, 2.3.0rc2,
2.3.0, 2.3.1, 2.3.2, 2.4.0rc0, 2.4.0rc1, 2.4.0rc2, 2.4.0rc3, 2.4.0rc4, 2.4.0, 2.4.1, 2.5.0rc0, 2.5.0rc1,
2.5.0rc2, 2.5.0rc3, 2.5.0) ERROR: No matching distribution found for tensorflow==2.0.0
只包含更高版本的。
2.尝试解决
https://blog.csdn.net/wsjzzcbq/article/details/101052960,根据这个添加清华源,
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ conda config --set show_channel_urls yes
不行,给出warining已经添加过了
Warning: 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/' already in 'channels' list, moving to the top
https://www.jianshu.com/p/777c7b7a3f3d,尝试设置防火墙ssl
conda config --set ssl_verify false
仍旧不行。
查看python版本为3.8,选择新建conda环境,废弃此环境。但尝试
仍然是这个报错:
Collecting package metadata (current_repodata.json): failed CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/linux-64/current_repodata.json> Elapsed: - An HTTP error occurred when trying to retrieve this URL. HTTP errors are often intermittent, and a simple retry will get you on your way. 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/linux-64'
无法连接到这个源,查看所有的源:
:~$ conda config --show-sources ssl_verify: False channels: - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/ - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/ - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro/ - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/ - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/ - defaults show_channel_urls: True
尝试使用浏览器访问
https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
本地windows可以访问,linux尝试通过命令来访问:
curl https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
也可以访问。
那么接下来尝试依次删掉上述源:
conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/ conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/ conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/pro/ conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/ conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/ conda config --show-sources ==> .condarc <== ssl_verify: False channels: - defaults show_channel_urls: True
将所有清华源都删除,终于出现了点不同的东西:
conda install tensorflow==2.0.0
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Collecting package metadata (repodata.json): done
Solving environment: |
输出可能有版本冲突的问题:
所以更改安装版本,根据cuda版本选择1.14.0
首先查看tensorboardx2.1依赖的torch版本:
目前我的版本是:
torch 1.8.1 tensorboardx 2.1
tensorboard 2.4.1
tensorflow 2.4.1
https://www.jianshu.com/p/058fba2c2530,这篇博文中提到,
tensorboardx在依旧需要tensorboard的支持 “To run tensorboard web server, you need to install it using: pip install tensorboard”.
而安装tensorboard需要安装tensorflow。所以会设计到版本依赖的问题。https://www.tensorflow.org/install/pip
当前环境的python版本是3.8,怪不得pip安装的时候只有2.2版本及以上的,找不到2.2。
所以决定新建一个conda环境,py版本3.7的。
将清华源都删除后,conda可以安装包了。。。。
