FractalSnowflake error when using conda installation

[jaclark5]

Describe the bug
When I install QCFractal and QCPortal with conda, and initiate the FractalSnowflake, I get the following error:

Process ForkProcess-2:
Traceback (most recent call last):
  File "/Users/jenniferclark/.local/share/mamba/envs/qca-clean/lib/python3.11/multiprocessing/process.py", line 314, in _bootstrap
    self.run()

    raise ValueError(f"Executor {ex} has no available programs")
ValueError: Executor local has no available programs

This doesn't happen when using pip.

To Reproduce
Install one of the two environments and run the following code:

from qcfractal.snowflake import FractalSnowflake
snowflake = FractalSnowflake()
client = snowflake.client()

name: qca-clean-works
channels:
  - conda-forge
dependencies:
  - python=3.11
  - numpy
  - jupyter
  - pandas
  - h5py
  - periodictable
  - pip:
      - qcportal==0.59
      - qcfractal==0.59
      - qcfractalcompute

name: qca-clean-fails
channels:
  - conda-forge
dependencies:
  - python=3.11
  - numpy
  - jupyter
  - pandas
  - h5py
  - periodictable
  - qcportal==0.59
  - qcfractal==0.59

Is this from within a jupyter notebook?

I had seen this before, but only when using using a Jupyter notebook from one environment but using a kernel from another environment (that has qcfractal installed). But it worked outside of jupyter.

I feel like having it work with pip is a hint. I do some not-so-pleasant multiprocessing things in a snowflake, and I'm not surprised it's brittle. My guess is something is going wrong with environments after forking.

I didn't do anything to my env and now it's running.... idk
