Hello, I am attempting to get started with integrating the Pulse engine into a Python project. The output I am getting from pulse.pull\_data() and pulse.print\_results() doesn’t make sense to me. All of the values are the same (seems to be SimulationTime). I am hoping there is something obvious I am missing. Below is my code and the output
```auto
def HowTo_Hemorrhage():
pulse = PulseEngine()
pulse.set_log_filename("./test_results/howto/HowTo_Hemorrhage.py.log")
pulse.log_to_console(True)
# NOTE: No data requests are being provided, so Pulse will return the default vitals data
if not pulse.serialize_from_file("../../builds/install/bin/states/Soldier@0s.json", None):
print("Unable to load initial state file")
return
# Get default data at time 0s from the engine
results = pulse.pull_data()
pulse.print_results()
# Perform an action
hemorrhage = SEHemorrhage()
hemorrhage.set_comment("Laceration to the leg")
hemorrhage.set_compartment(eHemorrhage_Compartment.RightLeg)
hemorrhage.get_severity().set_value(0.8)
# Optionally, You can set the flow rate of the hemorrhage,
# but this needs to be provided the proper flow rate associated with the anatomy
# This is implemented as a flow source, this rate will be constant, and will not be affected by dropping blood pressures
# It is intended to interact with sensors or with something continuously monitoring physiology and updating the flow
#hemorrhage.get_flow_rate().set_value(75,VolumePerTimeUnit.mL_Per_min)
pulse.process_action(hemorrhage)
# Advance some time and print out the vitals
pulse.advance_time_s(10)
results = pulse.pull_data()
pulse.print_results()
print(results)
pulse.advance_time_s(10)
results = pulse.pull_data()
pulse.print_results()
print(results)
pulse.advance_time_s(10)
results = pulse.pull_data()
pulse.print_results()
print(results)
# For this example, you will see a decrease in blood volume
HowTo_Hemorrhage()

Hi @jdyreson
We are about to push out our latest release to the stable branch.
Would you be able to pull our [latest release updates branch](https://gitlab.kitware.com/physiology/engine/-/tree/feature/release_updates/src?ref_type=heads) and test out the python capabilities there?
I think it should be a bit more well behaived
Any feedback would be appreciated!
