Stuck while training at 977 itr

[zusne]

I choose the point_gather, and use rllab to train 5000 itr, but it always get stuck when it come to 977 itr. I try to train 8 programs with different parameters in parallel, but all get stuck at 977 itr, and i turn to train only one program, get the same result. I think thers is something wrong with my computer, so i change a computer to train the same program 5000 itr, but also get the same result: get stuck while training at 977. I am so comfused about it. All the progeams will stuck like this:

all thing seem to stop, but no error report. I wonder why, or is there some way to load the param about the trained model before?
