Unable to use gravityspy as a package to classify trigger events

[rutujagurav]

Summary

I want to follow this gravityspy documentation page to classify a trigger, so I am trying to install gravityspy following the installation instructions in the documentation but I am getting an error ERROR: Could not find a version that satisfies the requirement mysqlclient>=1.4.0 (from gravityspy). I tried installing mysqlclient in my conda environment separately but I still get this error.

I also tried using the existing environment that has the gravityspy package installed which is found here on ldas machines - /home/gravityspy/.conda/envs/gravityspy-gpu-py37/ - but the example code in the documentation didn't run successfully and produce the following error,

(gravityspy-gpu-py37) [rutuja.gurav@ldas-pcdev6 ~]$ python test_gravityspy.py

What should have happened?

The example code from the documentation should have run successfully

Steps to reproduce

In a terminal on ldas-pdev6.ligo-la.caltech.edu, run command conda activate /home/gravityspy/.conda/envs/gravityspy-gpu-py37/

Then run the following lines of python code,

from gravityspy.classify import classify
event_time = 1127700030.877928972
model_filepath = '/home/gravityspy/GravitySpy/models/similarity-model-O3.h5'
results = classify(event_time=event_time,
                    channel_name='L1:GDS-CALIB_STRAIN',
                    path_to_cnn=model_filepath)
print(results)
