Hi! I am trying to make call with the nds2 client from Google colab. So far I failed because the nds2 module does not appear to be installed automatically by pip. The following lines: > ! pip install -q ‘gwpy==3.0.4’ > from gwpy.timeseries import TimeSeries > data = TimeSeries.fetch(‘L1:ISI-GND\_STS\_ITMY\_Z\_BLRMS\_30M\_100M’, start=1263229218, end=1263229228, host=‘[losc-nds.ligo.org](http://losc-nds.ligo.org)’) results in the following error: > → 308 import nds2 > 309 # pylint: disable=no-member > 310 > > ModuleNotFoundError: No module named ‘nds2’ The nds2 client packages do not seem to be available with pip: > !pip install nds2-client python-nds2-client > Looking in indexes: [Simple index](https://pypi.org/simple), [https://us-python.pkg.dev/colab-wheels/public/simple/](https://us-python.pkg.dev/colab-wheels/public/simple/) > ERROR: Could not find a version that satisfies the requirement nds2-client (from versions: none) > ERROR: No matching distribution found for nds2-client Any hint?

@ecm That’s right. The NDS2 client is currently packaged for conda, but not pypi. This is a problem for cloud platforms like Google Co-lab that rely on pip to install packages. I have the same problem on `streamlit`, which also relies on `pip`. I don’t have a solution, other than to request that the NDS2 client be packaged for `pypi`. You could add a ticket for that (and/or send an email), here: > **[nds / nds2-client · GitLab](https://git.ligo.org/nds/nds2-client)** > > C/C++/Python/Matlab/Octave/Java clients for retrieving data from NDS servers. This repository contains historic information, but for client 0.15.2 and earlier the SVN is considered canonical. ---

Thank you @jonah ! I’ve opened a ticket. E. ---

Any update on being able to use nds2 on Colab? ---

I did ```auto !pip install -q condacolab import condacolab condacolab.install() !conda install -c conda-forge python-nds2-client ``` That seems to have worked for now for colab notebook ---

Hi! I’m also trying to use nds2 on google collab. aghalsa’s suggestion `!pip install -q condacolab` `import condacolab` `condacolab.install()` `!conda install -c conda-forge python-nds2-client` worked, but I still cannot `import nds2` getting ```auto ModuleNotFoundError: No module named 'nds2' ``` What do I miss? ---

i think you need to import python-nds2-client as nds2
