"libstdc++.so.6: version `GLIBCXX_3.4.22' not found"

Hi,

I am running into a trouble for "libstdc++.so.6: version `GLIBCXX_3.4.22' not found" issue.

I was trying to run python sklearn in R cloud. sklearn was successfully installed, but when I was trying to run:

"

import numpy as np
import matplotlib.pyplot as plt

from sklearn.datasets import make_blobs
from sklearn.discriminant_analysis import LinearDiscriminantAnalysis

I got the error message:
"ImportError: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by /home/rstudio-user/.local/share/r-miniconda/envs/py3.8/lib/python3.8/site-packages/scipy/fft/_pocketfft/pypocketfft.cpython-38-x86_64-linux-gnu.so)"

It seems that "libstdc++.so.6: version `GLIBCXX_3.4.22'" not found... does anyone know how should I solve this problem?

The project url is:

Thanks,

This means that your Python package requires a newer version of of libstdc++.so.6 than what is currently available on rstudio.cloud:

rstudio-user@application-2196984-deployment-5855589-vvf7h:/cloud/project$ strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

Try installing the package from source and have it compile on rstudio.cloud itself.

Thanks Josh. Could you please provide more details on how to install the package from source? I was trying to type 'sudo apt-get install libstdc++6' in my terminal but it popped up "password for rstudio-user" and I don't think I have setup that password before...
Thanks so much, any details will be highly appreciated!

Hi Gosh, I checked and got to know that "GLIBCXX_3.4.21" is the latest version in my cloud. I need to install "GLIBCXX_3.4.22" in order to run those Python packages. I read some posts and I realize that I may not have permission to use sudo command to install "GLIBCXX_3.4.22" in my terminal. As you said, the only way I can get this install is to manually download it on my own and compile in my could, correct?

If my understanding is correct, can you provide some guidelines/instructions on how to do that so I can follow?

Thanks a lot!
Li

Don't install Python wheels. Install the Python package from source and compile it in rstudio.cloud.
You are not able to install or update libstdc++.
