Hello everybody,

I am currently on a project where we intend to use fireworks as our workflow manager. I have installed everything but I am having “Module not find” errors when trying to do a `rlaunch rapidfire`

. This is my example code:

```
from fireworks import Firework, Workflow, LaunchPad, PyTask
import numpy
from matrix_operations import multiply_by_two, divide_by_two, subtract_half
initial_matrix = numpy.ones((30, 30))
fw1 = Firework(PyTask(func='matrix_operations.multiply_by_two', args=[initial_matrix, 2], stored_data_varname='result'), name="multiply_by_two")
fw2 = Firework(PyTask(func='matrix_operations.divide_by_two', stored_data_varname='result', args=[initial_matrix, 2]), name="divide_by_two")
fw3 = Firework(PyTask(func='matrix_operations.subtract_half', stored_data_varname='result', args=[initial_matrix, 0.5]), name="subtract_half")
# Define dependencies between the FireWorks
dependencies = {fw1: [fw2], fw2: [fw3]}
# Create the workflow
wf = Workflow([fw1, fw2, fw3], dependencies)
# Connect to the FireWorks database and add the workflow
lp = LaunchPad()
lp.add_wf(wf)
```

And this is the matrix_operations:

```
# matrix_operations.py
import numpy as np
def multiply_by_two(matrix):
return matrix * 2
def divide_by_two(matrix):
return matrix / 2
def subtract_half(matrix):
return matrix - 0.5
def save_result(matrix, filename="final_matrix.txt"):
np.savetxt(filename, matrix)
print(f"Matrix saved to {filename}")
```

Both files are in the same working directory. I know I could use numpy (and in this case, the import works) for these operations, but I wanted an example like this, since I will be using our in-house functions for the operations.

Below is the error message:

Thanks in advance for any tip that might get me further on this problem.
