ValueError: Number of processes must be at least 1

[wonyoungtae]

When I attempted to use RoseTTAFold, I encountered the following error at the end.

$ nano /log/pick.stderr

Traceback (most recent call last):
  File "/home/yt/RoseTTAFold/DAN-msa/pick_final_models.div.py", line 113, in <module>
    pool = mp.Pool(n_core_pool)
  File "/home/yt/anaconda3/envs/folding/lib/python3.7/multiprocessing/context.py", line 119, in Pool
    context=self.get_context())
  File "/home/yt/anaconda3/envs/folding/lib/python3.7/multiprocessing/pool.py", line 169, in __init__
    raise ValueError("Number of processes must be at least 1")
ValueError: Number of processes must be at least 1

How can I solve this problem?

Seems caused of the conflicts among python 3.7, tensorflow, numpy, and so on. Same as #135

Hello, I did the following instruction.
[#135]

However, then i got new error like this:

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/mnt/D/RoseTTAFold-1.1.0/DAN-msa/pick_final_models.div.py", line 114, in <module>
    raw_dist = pool.map(calc_lddt_dist, args)

  File "/home/ypkim/miniconda3/envs/folding/lib/python3.7/multiprocessing/pool.py", line 657, in get
    raise self._value

Is there anyone can solve this problem?

Thank you.
