   It seems the TRT setting the device properly. If you accept a dirty workaround try replace ctx = mx.gpu(1) with these: 
   `from ctypes import cdll, c_char_p
   libcudart = cdll.LoadLibrary('libcudart.so')
   libcudart.cudaGetErrorString.restype = c_char_p
   def cudaSetDevice(device_idx):
       ret = libcudart.cudaSetDevice(device_idx)
       if ret != 0:
           error_string = libcudart.cudaGetErrorString(ret)
           raise RuntimeError("cudaSetDevice: " + error_string)
   
   device_id = 1
   cudaSetDevice(device_id)`
