Python Script from PHP - php

Question

I am running a Python script from a PHP file. For a very a simple example, it works perfectly. Here is the Python script:
#!/usr/bin/env python
def test():
x = 2 + 1
print x + 4
return x
print test()
And PHP script:
<?php
$command = escapeshellcmd('/usr/bin/python2.7 /home/super/PycharmProjects/img_plus_text/helloworld.py');
$output = shell_exec($command);
echo $output;
echo "Finishing....!";
?>
Unfortunately, for more complicated script, It does not work. Here is the Python script
#!/usr/bin/env python
import numpy as np
import os
import random
import caffe
import cv2
from sklearn.externals import joblib
import create_dataset_final_mlp
import text_2_bow
def create_class_mapping():
with open("text_processing/encoded-classes.txt") as class_file:
lines = class_file.readlines()
dictionary = {}
for item in lines:
item = item.split(" ")
dictionary[item[0]] = item[1].replace("\n", "").replace("#", "")
return dictionary
def get_top5(probability_list):
result = []
probabilities = []
for i in range(0, 5):
top = probability_list.index(max(probability_list))
probabilities.insert(i, probability_list[top])
probability_list[top] = -1
result.insert(i, top)
return result, probabilities
def select_random_file(base_dir):
# Select random category
file_chosen = random.choice(os.listdir(base_dir))
# Select random file in that category
file_chosen = random.choice(os.listdir(base_dir + "/" + file_chosen))
return file_chosen
def get_top5_class_name(mapping, top5_list):
class_name_list = []
for i in range(0, 5):
index = top5_list[i]
class_name = mapping[str(index)]
class_name_list.insert(i, class_name)
return class_name_list
def main(image_to_classify):
dataset_path = "/images-test1"
image_file_chosen = create_dataset_final_mlp.find(image_to_classify, dataset_path)
if image_file_chosen is None:
image_file_chosen = select_random_file("%s" % dataset_path)
identifier = image_file_chosen.split(".")[0]
print "Identifier: " + identifier

# load the final MLP to classify patterns
print "loading model from disk..."
mlp = joblib.load("trained_model_9097_5000_3000_iter_100.model")
with open("export-ferramenta.csv") as export_file:
for line in export_file:

break
# Show selected image
full_img_path = create_dataset_final_mlp.find(image_file_chosen, dataset_path)
# img = cv2.imread(full_img_path, cv2.IMREAD_COLOR)
# cv2.imshow("Image selected", img)
# cv2.waitKey(0)
# get the CNN features
inputs = [caffe.io.load_image(full_img_path)]
# the second parameter is used to switch for prediction from center crop alone instead of averaging predictions across crops (default).
classifier.predict(inputs, False)
features = classifier.blobs['fc6'].data[0]
extracted_cnn_features = create_dataset_final_mlp.get_cnn_features_as_vector(features)
extracted_cnn_features = extracted_cnn_features[:-1]
extracted_cnn_features = extracted_cnn_features.split(",")
# transform the text using text_2_bow functions
pattern = pattern.split(",")
text_pattern = pattern[1] + pattern[2]
matrix = text_2_bow.get_matrix(text_pattern, dictionary)
reshaped_matrix = np.reshape(matrix, 5000).tolist()
full_features_vector = extracted_cnn_features + reshaped_matrix
full_features_vector = np.asarray(full_features_vector, np.float64)
# use the MLP to classify
prediction = mlp.predict_proba([full_features_vector])
tolist = prediction[0].tolist()
mapping = create_class_mapping()
top5, probabilities = get_top5(tolist)
top_class_name = get_top5_class_name(mapping, top5)
print "Top 5 classes: ", top_class_name
print "Top 5 probs ", probabilities
return top_class_name, probabilities
if __name__ == "__main__":
main("")
PHP Script
<?php
echo exec('sudo /home/super/bin/caffe-nv/python /home/super/PycharmProjects/img_plus_text/demo_website.py 2>&1');
?>
ERROR

I have read majority of the questions on the issue however I am stuck here. Please point out the mistake. Thank you.

Answer 1

The problem was with environment variables, I made a shell script as shown below
export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/:$LD_LIBRARY_PATH
export PYTHONPATH=$PYTHONPATH:/home/super/bin/caffe-nv/python/
python /demo_website2.py $1
Then I run the shell script from PHP using exec
exec("/opt/lampp/htdocs/test/run.sh ". $param, $output);
