"unknown option for --cudapath" when installing the standalone worker

**Hi, **
I have install cryopsarc master and I have a problem for the worker module, when I want to install it I have this error message in the terminal

/programs/cryosparc/cryosparc2_worker$ ./install.sh --license $LICENSE_ID --cudapath /usr/local/cuda-9.2/
Unknown option: /usr/local/cuda-9.2/

however cuda seems to be correctly installed
I use Ubuntu 16.04
my graphic cards inxi profile

/programs/cryosparc/cryosparc2_worker$ inxi -G
Graphics: Card-1: NVIDIA GM200 [GeForce GTX 980 Ti]
_ Card-2: NVIDIA GM200 [GeForce GTX 980 Ti]_
_ Card-3: NVIDIA GM200 [GeForce GTX 980 Ti]_
_ Display Server: X.Org 1.19.6 drivers: nvidia,nouveau (unloaded: fbdev,vesa)_
_ Resolution: 2560x1080@60.00hz_
_ GLX Renderer: GeForce GTX 980 Ti/PCIe/SSE2_
_ GLX Version: 4.6.0 NVIDIA 396.51_

however when i try to list gpu available

/programs/cryosparc/cryosparc2_worker$ bin/cryosparcw gpulist
Traceback (most recent call last):
_ File “”, line 1, in _
_ File “connect.py”, line 6, in print_gpu_list_
_ import pycuda.driver as cudrv_
ImportError: No module named pycuda.driver

any helps will be welcome. If you had the same issue previously, i will be glad to have your support


Can you double check if your $LICENSE_ID environment variable is set?
If it comes up empty, this is probably why this command is failing. You should re-set this variable using
export LICENSE_ID="<license_id>"
and then try the install command again.

Good luck,

thanks you, adding the LICENSE_ID again solved my problem
I have reinstall the worker module because I was previously able to install it with this command

_/programs/cryosparc/cryosparc2worker$ ./install.sh --license $LICENSE_ID --cudapath --nogpu
