Re: [Rdkit-discuss] Problems with conda intall on Google Colab (2)

[Fuji, H. <hid...@as...>]

Hi Kazu,

I faced with the same error recently.
In my case, I decided to use previous version of RDKit in Google Colab as follows.

conda install -q -y -c conda-forge rdkit==2020.03.6

I hope it is helpful for you.

Best regards,

Hideyoshi

Dear All,


I was able to use RDKit with Google Colaboratory until December 13th, but
on December 20th I got the following message and could not use it.

ImportError: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version
`GLIBCXX_3.4.26' not found

When I checked with
strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX,
the result was as follows.

GLIBCXX_3.4
GLIBCXX_3.4.1
%
GLIBCXX_3.4.25
GLIBCXX_DEBUG_MESSAGE_LENGTH

So I executed the following:

%%bash
add-apt-repository ppa:ubuntu-toolchain-r/test -y
apt-get update
apt-get install gcc-4.9
apt-get upgrade libstdc++6

Again, when I checked with
strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX,
the result was as follows.

GLIBCXX_3.4
GLIBCXX_3.4.1
%
GLIBCXX_3.4.26
GLIBCXX_3.4.27
GLIBCXX_3.4.28
GLIBCXX_DEBUG_MESSAGE_LENGTH

However, I still get the same error when importing RDKit, although GLIBCXX_3.4.26
is installed.

ImportError: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version
`GLIBCXX_3.4.26' not found

Currently, I cannot use RDKit.
I would be grateful if you could give me a hint as to how to solve it.

Best regards, Kazu
