Cannot install google-colab for 02_ddsp

[alexdrymonitis]

I'm following the steps for building the second example, 02_ddsp, and I'm getting stuck in pip install google-colab.
The errors start when it's trying to build pandas. I've uploaded the output which I got with pip install google-colab 2> colab_error.txt
I'm on UbuntuStudio 21.04. I created the Conda environment with conda create -n ddsp python=3.8 tensorflow=2.4.1 tensorflow-probability pandas=0.25
Because using pandas=0.24 was giving me incompatibility errors with Python3.8.

seems related to pandas-dev/pandas#34969, maybe installing an older numpy version would do as a workaround. i believe there's been some work in upstream ddsp to factor out the colab dependency, but our code still needs corresponding updates and unfortunately it will be some time before we get to that.
