Hi, i’m trying to run xgboost\_ray on a Ray cluster deployed on K8. The connection to the K8 cluster works properly but when I try to run xgboost\_ray I get `"Exception iterating responses: No module named 'xgboost_ray'"` . I’m using the Ray Kubernetes Operator and the Docker image I used to deploy Ray on the K8 cluster is `"rayproject/ray-ml"` Here my code and error. Thanks in advance for your help.

```
import ray
import ray.util
import os
import time
from xgboost_ray import train, RayDMatrix, RayParams
import pandas as pd
ray.util.connect("127.0.0.1:50051") 
colnames = ["label"] + ["feature-%02d" % i for i in range(1, 29)]
df = pd.read_csv("HIGGS.csv.gz", names=colnames)
dtrain = RayDMatrix(df, label="label",)
config = {
    "tree_method": "hist",
    "eval_metric": ["logloss", "error"],
}
evals_result = {}
start = time.time()
bst = train(
    config,
    dtrain,
    evals_result=evals_result,
    ray_params=RayParams(max_actor_restarts=1),
    num_boost_round=100,
    evals=[(dtrain, "train")])
taken = time.time() - start
print(f"TRAIN TIME TAKEN: {taken:.2f} seconds")
bst.save_model("higgs.xgb")
print("Final training error: {:.4f}".format(
    evals_result["train"]["error"][-1]))

```
