os.process 在 apache2 中加载 usr/sbin/ 并且无法识别命令（模块）
os.process on apache2 loads in usr/sbin/ and does not recognise command (module)
我正在尝试 运行 我在 apache2 服务器上托管的烧瓶应用程序中的子进程命令。
当我 运行 子进程（确认代码在 apache2 之外工作）时：
@app.route("/ScanResult")
def scan_result():
process = subprocess.run('face_recognition ./known_faces/ ./unknown_faces/', shell=True, check=True,
stdout=subprocess.PIPE, universal_newlines=True)
output = process.stdout
flash(output)
return render_template("scanresult.html")

我开始检查似乎与点击模块有关的错误。 unix bytes not unicode issue
如果我可以 运行 在终端中做到这一点，我应该能够通过我的烧瓶应用 运行 它肯定可以，不是吗？

我已经尝试了建议的解决方案：
export LC_ALL = en_US.utf-8
export LANG = en_US.utf-8
插入到.py文件的开头。导致错误：

如何修改我的 sub.process 以匹配建议的解决方案：
Instead you need to do this:
input = 'Input here'
in_stream = io.BytesIO(input.encode('utf-8'))
sys.stdin = io.TextIOWrapper(in_stream, encoding='utf-8')
out_stream = io.BytesIO()
sys.stdout = io.TextIOWrapper(out_stream, encoding='utf-8')
This causes problems if the terminal is incorrectly set and Python does not figure out the encoding. In that case, the Unicode string will contain error bytes encoded as surrogate escapes.
我需要更改语言环境吗？
我的语言环境：
(apache_flask_venv) thomas@apacheflask:/var/www/webApp/webApp$ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
将语言环境修改为建议的，没有任何错误。
(apache_flask_venv) thomas@apacheflask:/var/www/webApp/webApp$ locale
LANG=C.UTF-8
LANGUAGE=
LC_CTYPE="C.UTF-8"
LC_NUMERIC="C.UTF-8"

LC_ADDRESS="C.UTF-8"
LC_TELEPHONE="C.UTF-8"
LC_MEASUREMENT="C.UTF-8"
LC_IDENTIFICATION="C.UTF-8"
LC_ALL=C.UTF-8
到目前为止，我为这个问题找到的唯一解决方案是使用 python2 而不是 python3 - 这需要将所需的 dlib 和 face_recognition 安装到 python2 环境然后在命令之前调用 python2.6.
取而代之，我创建了一个复制 command-line 工具功能的方法。
unknown_images = os.listdir("/var/www/Webapp/webApp/scan/")
for unknown_image in unknown_images:
loaded_image = face_recognition.load_image_file(unknown_image)
query_faces = face_recognition.face_encodings(loaded_image)
faces_found = len(query_faces)
faces = []
if faces_found:
faces_dict = get_faces_dict("/var/www/Webapp/webApp/faces/")
face_encodings = list(faces_dict.values())
for query_face in query_faces:
match_results = face_recognition.compare_faces(
face_encodings, query_face)
for idx, match in enumerate(match_results):
if match:
match = list(faces_dict.keys())[idx]
match_encoding = face_encodings[idx]
dist = face_recognition.face_distance([match_encoding], query_face)[0]
faces.append({
"Filename":str(unknown_image),
"Name": match,
"Accuracy": dist
})
flash("Scan Results: " + str(faces))
如果有人有解决与语言环境变量相关问题的完整解决方案，请post。除了 re-installing 和在 python2 环境中构建之外，修改 LANG 等的建议解决方案不起作用。

我开始检查似乎与点击模块有关的错误。 unix bytes not unicode issue
如果我可以 运行 在终端中做到这一点，我应该能够通过我的烧瓶应用 运行 它肯定可以，不是吗？
(apache_flask_venv) thomas@apacheflask:/var/www/webApp/webApp$ face_recognition ./faces/ ./scan/
Dlib was compiled to use SSE41 instructions, but these aren't available on your machine.
./scan/singleperson.jpg,singleperson
我已经尝试了建议的解决方案：
export LC_ALL = en_US.utf-8
export LANG = en_US.utf-8
插入到.py文件的开头。导致错误：

如何修改我的 sub.process 以匹配建议的解决方案：
Instead you need to do this:
input = 'Input here'
in_stream = io.BytesIO(input.encode('utf-8'))
sys.stdin = io.TextIOWrapper(in_stream, encoding='utf-8')
out_stream = io.BytesIO()
sys.stdout = io.TextIOWrapper(out_stream, encoding='utf-8')
This causes problems if the terminal is incorrectly set and Python does not figure out the encoding. In that case, the Unicode string will contain error bytes encoded as surrogate escapes.
我需要更改语言环境吗？
我的语言环境：
(apache_flask_venv) thomas@apacheflask:/var/www/webApp/webApp$ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
将语言环境修改为建议的，没有任何错误。
(apache_flask_venv) thomas@apacheflask:/var/www/webApp/webApp$ locale
LANG=C.UTF-8
LANGUAGE=
LC_CTYPE="C.UTF-8"
LC_NUMERIC="C.UTF-8"
LC_TIME="C.UTF-8"
LC_COLLATE="C.UTF-8"
LC_MONETARY="C.UTF-8"
LC_MESSAGES="C.UTF-8"
LC_PAPER="C.UTF-8"

LC_ADDRESS="C.UTF-8"
LC_TELEPHONE="C.UTF-8"
LC_MEASUREMENT="C.UTF-8"
LC_IDENTIFICATION="C.UTF-8"
LC_ALL=C.UTF-8
到目前为止，我为这个问题找到的唯一解决方案是使用 python2 而不是 python3 - 这需要将所需的 dlib 和 face_recognition 安装到 python2 环境然后在命令之前调用 python2.6.
取而代之，我创建了一个复制 command-line 工具功能的方法。
unknown_images = os.listdir("/var/www/Webapp/webApp/scan/")
for unknown_image in unknown_images:
loaded_image = face_recognition.load_image_file(unknown_image)
query_faces = face_recognition.face_encodings(loaded_image)
faces_found = len(query_faces)
faces = []
if faces_found:
faces_dict = get_faces_dict("/var/www/Webapp/webApp/faces/")
face_encodings = list(faces_dict.values())
for query_face in query_faces:
match_results = face_recognition.compare_faces(
face_encodings, query_face)
for idx, match in enumerate(match_results):
if match:
match = list(faces_dict.keys())[idx]
match_encoding = face_encodings[idx]
dist = face_recognition.face_distance([match_encoding], query_face)[0]
faces.append({
"Filename":str(unknown_image),
"Name": match,
"Accuracy": dist
})
flash("Scan Results: " + str(faces))
如果有人有解决与语言环境变量相关问题的完整解决方案，请post。除了 re-installing 和在 python2 环境中构建之外，修改 LANG 等的建议解决方案不起作用。
