MulticoreTSNE安裝極易報錯

ModuleNotFoundError: No module named 'MulticoreTSNE'

需先進(jìn)行特定版本的cmake安裝

pip install cmake==3.18.4

然后

pip install?MulticoreTSNE

在實際運(yùn)行的時候報錯

Cannot find/open tsne_multicore shared library

cannot load library '/xxxx/miniconda3/xxx/site-packages/MulticoreTSNE/libtsne_multicore.so':

?/xxxx/miniconda3/xxx/site-packages/scipy/_lib/_uarray/../../../../../libstdc++.so.6: version `GLIBCXX_3.4.29' not found

?(required by /xxxx/miniconda3/xxx/site-packages/MulticoreTSNE/libtsne_multicore.so)

確認(rèn)錯誤來源

$ real path /xxxxx/miniconda3/xxx/scipy/_lib/_uarray/../../../../../libstdc++.so.6

$ /xxxx/miniconda3/xxx/lib/libstdc++.so.6.0.26

$ strings /xxxx/miniconda3/xxx/lib/libstdc++.so.6.0.26? | grep GLIBCXX_3.4.29

$ # return nothing

查找miniconda中有的動態(tài)庫

find /home/xxx/tools/miniconda3 -name libstdc++.so.6

strings /home/xxx/tools/miniconda3/envs/i2v/lib/libstdc++.so.6 | grep GLIBCXX_3.4.29

找到后進(jìn)行替換

$ mv /xxxx/miniconda3/xxx/lib/libstdc++.so.6.0.26 /xxxx/miniconda3/xxx/lib/libstdc++.so.6.0.26_bak

$ ln -s /usr/lib/libstdc++.so.6.0.29 /xxxx/miniconda3/xxx/lib/libstdc++.so.6.0.26

再次運(yùn)行就可以了。

因此可以從頭開始，

pip uninstall cmake

pin install cmake

pip uninstall multicoretsne

pip install MulticoreTSNE

按照前述的方法替換GLIBCXX_3.4.29

重新加載python環(huán)境再次運(yùn)行即可。
