./install_sim.sh viz

Verify Vizier Installation

Run the following:

python ./vizier_verify.py

The output should look like this:

Optimal Trial Suggestion and Objective: ParameterDict(_items={‘bypass’: False, ‘cfu’: True, ‘hardwareDiv’: True, ‘mulDiv’: True, ‘singleCycleShift’: True, ‘singleCycleMulDiv’: True, ‘safe’: False, ‘prediction’: none, ‘iCacheSize’: 8192.0, ‘dCacheSize’: 8192.0}) Measurement(metrics={‘cycles’: Metric(value=0.0, std=None), ‘cells’: Metric(value=0.0, std=None)}, elapsed_secs=0.0, steps=0) Optimal Trial Suggestion and Objective: ParameterDict(_items={‘bypass’: False, ‘cfu’: True, ‘hardwareDiv’: True, ‘mulDiv’: False, ‘singleCycleShift’: True, ‘singleCycleMulDiv’: False, ‘safe’: False, ‘prediction’: none, ‘iCacheSize’: 4096.0, ‘dCacheSize’: 16384.0}) Measurement(metrics={‘cycles’: Metric(value=0.0, std=None), ‘cells’: Metric(value=0.0, std=None)}, elapsed_secs=0.0, steps=0)

Fixes for some common errors while Vizier installation

  1. Errors related to “cvxopt” can be fixed using the following commands:

pip install cvxopt
export CVXOPT_BUILD_FFTW=1
pip install cvxopt --no-binary cvxopt
conda install -c conda-forge cvxopt

  1. “No module named emukit”

pip install emukit

If pip install emukit throws an error related to gcc compiler, then try installing it using this -

sudo apt update && sudo apt install -y build-essential

You may further encounter errors related to : E: Could not open lock file /var/lib/ dpkg/lock-frontend - open (13:Permission denied) E: Unable to acquire the dpkg frontend lock /var/lib/dpkg/lock-frontend, are you root?

To solve this follow this :

sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock*
sudo apt update

Run this again :

sudo apt update && sudo apt install -y build-essential

Gcc installation is done, now you can proceed with pip install emukit Now try running vizier_dse.py again. It should run without errors.
