I used the following example code received from chatGPT when asking "error ObjectRef in ray.get after ray.put". The model suggested this code example should work, but it doesn't:

import ray

ray.init()

# Store a large object in Ray
data = [i for i in range(10**6)]
data_ref = ray.put(data)

# Define a task that uses the stored object
@ray.remote
def process_data(ref, start, end):
data = ray.get(ref) # Retrieve the object
return sum(data[start:end])

# Launch parallel tasks using the ObjectRef
tasks = [process_data.remote(data_ref, i * 100000, (i + 1) * 100000) for i in range(10)]
results = ray.get(tasks) # Fetch results
print(f"Total sum: {sum(results)}")


I get the following error: TypeError: Attempting to call get on the value 0, which is not an ray.ObjectRef

both print(type(data_def) and print(type(tasks[0]) give <class 'ray._raylet.ObjectRef'> but while ray.get(data_ref) gives an array of numbers ray.get(tasks[0]) produces the above mentioned error
