9 years ago Hi Mohammad, sorry, I'm sure that's frustrating. I think it's probably a good idea to get in touch with your cluster admin. At the moment it looks to me like they may be preventing you from spawning processes on the cluster (through the fork command). In that case, you may want to try to launch mongodb from a separate node in the cluster (you'll have to point to that machine in spearmint) or keep one terminal open in the cluster and running mongodb without fork.

Dear all I'm trying to use Spearmint package on the cluster and I have the following problem for running the "simple" in examples! (I have to mention that, I have tested this example on my laptop successfully!)
When I first try to execute the command "mongod --fork --logpath --dbpath" in the simple example folder, I have the following error;
############################ about to fork child process, waiting until server is ready for connections. forked process: 108120 all output going to: /home/mehrianmohammad/Spearmint-master/examples/simple/--dbpath log file [/home/mehrianmohammad/Spearmint-master/examples/simple/--dbpath] exists; copied to temporary file [/home/mehrianmohammad/Spearmint-master/examples/simple/--dbpath.2015-06-02T14-32-33] ERROR: child process failed, exited with error number 100 ##############################
Jasper suggested that I delete fork in the above command, and when I tried, there is no error! So, I moved to the spearmint folder and then execute the command: "python main.py ../examples/simple" but there is an error;
###################### Traceback (most recent call last): File "main.py", line 198, in from spearmint.utils.database.mongodb import MongoDB ImportError: No module named spearmint.utils.database.mongodb #######################
So, as Jasper suggested again!, I installed Spearmint package one more time in the spearmint folder, using the command; "pip install -e." but nothing changes!!!
I have to mention that, I do NOT see all these errors when I log into the cluster with admin user!! (With admin user, it works properly!) So, As Jasper (Thanks for his time) suggested, I installed Anaconda on the cluster...but nothing changed! So, definitely the problem is that I am NOT the admin on the cluster! I'm wondering if anybody have any suggestion?
Best wishes, Mohammad
