Can't map SHM failed: Permission denied

[thempp66]

I found my code show the errors below. Would you help me to find the reason?
error:

OMP: Error #179: Function Can't map SHM failed:
OMP: System error #13: Permission denied

Code:

from sklearn.datasets import make_classification
from sklearn.model_selection import train_test_split
import time

# data pre-process
x, y = make_classification(n_samples=100, class_sep=2, n_features=30, random_state=42)
X_train, X_test, y_train, y_test = train_test_split(
    x, y, test_size=0.2, random_state=42
)

from sklearn.tree import DecisionTreeClassifier

# train
start_time = time.time()
model = DecisionTreeClassifier()
model.fit(X_train, y_train)
print("DecisionTreeClassifier train timecost(ms) : ", (time.time() - start_time) * 1000)
start_time = time.time()

# inference
result = model.predict(X_test)
# print("result : ", result)
print("DecisionTreeClassifier predict timecost(ms) : ", (time.time() - start_time) * 1000)

from concrete.ml.sklearn import DecisionTreeClassifier as cc_DecisionTreeClassifier

# Lets create a synthetic data-set
start_time = time.time()
model = cc_DecisionTreeClassifier(n_bits=8)
model.fit(X_train, y_train)
model.compile(X_train)
print("cc_DecisionTreeClassifier train timecost(ms) : ", (time.time() - start_time) * 1000)

start_time = time.time()
result = model.predict(X_test, fhe="execute")
# print("result : ", result)
print("cc_DecisionTreeClassifier predict timecost(ms) : ", (time.time() - start_time) * 1000)
