[英]LINK : fatal error LNK1104: cannot open file 'C:\Users\hp\.pyxbld\lib.win32-2.7\gensim\models\word2vec_inner.pyd'
我运行TWE模型的源代码。 我需要编译python的C扩展。 我已经为Python 2.7和Cython安装了Microsoft Visual C ++编译器。
首先,我需要运行TWE / train.py:
import gensim
sentence_word = gensim.models.word2vec.LineSentence("tmp/word.file")
print "Training the word vector..."
w = gensim.models.Word2Vec(sentence_word,size=400, workers=20)
sentence = gensim.models.word2vec.CombinedSentence("tmp/word.file","tmp/topic.file")
print "Training the topic vector..."
w.train_topic(topic_number, sentence)
print "Saving the topic vectors..."
w.save_topic("output/topic_vector.txt")
print "Saving the word vectors..."
w.save_wordvector("output/word_vector.txt")`
二,TWE / gensim / models / wor2vec.py:
try:
raise ImportError # ignore for now
from gensim_addons.models.word2vec_inner import train_sentence_sg,train_sentence_cbow, FAST_VERSION, train_sentence_topic
except ImportError:
try:
import pyximport
print 'import pyximport'
models_dir = os.path.dirname(__file__) or os.getcwd()
print 'models_dir'
pyximport.install(setup_args={"include_dirs": [models_dir, get_include()]})
print 'pyximport' # is the follow code's problem
from word2vec_inner import train_sentence_sg, train_sentence_cbow,
FAST_VERSION, train_sentence_topic
print 'from word2vec'
except:
FAST_VERSION = -1
def train_sentence_sg(model, sentence, alpha, work=None):
...
def train_sentence_cbow(model, sentence, alpha, work=None, neu1=None):
...
class Word2Vec(utils.SaveLoad):
...
def train(self, sentences, total_words=None, word_count=0, chunksize=100):
if FAST_VERSION < 0:
import warnings
warnings.warn("Cython compilation failed, training will be slow. Do you have Cython installed? `pip install cython`")
logger.info("training model with %i workers on %i vocabulary and %i features, "
"using 'skipgram'=%s 'hierarchical softmax'=%s 'subsample'=%s and 'negative sampling'=%s" %
(self.workers, len(self.vocab), self.layer1_size, self.sg, self.hs, self.sample, self.negative))
def worker_train():
...
if self.sg:
job_words = sum(train_sentence_topic(self, sentence, alpha, work) for sentence in job)
else:
ob_words = sum(train_sentence_cbow(self, sentence, alpha, work, neu1) for sentence in job)`
...
Thrid,我用setup.py编译了TWE / gensim / models / word2vec_inner.pyx:
from distutils.core import setup
from distutils.extension import Extension
from Cython.Build import cythonize
import numpy
extensions = [
Extension("word2vec_inner", ["word2vec_inner.pyx"],
include_dirs=[numpy.get_include()])
]
setup(
name="word2vec_inner",
ext_modules=cythonize(extensions),
)
通过使用命令'python setup.py install',我已经编译了word2vec_inner.pyx。 但它似乎出现以下错误:

我已检查.pyx文件是否已正确编译并安装了cython。 总之,它无法从gensim / models / word2vec_inner或gensim_addons / models / word2vec_inner导入train_sentence_sg,train_sentence_cbow,FAST_VERSION,train_sentence_topic。 所以看来这些问题。 但为什么? 我已经在两个方向上正确编译了.pyx文件。 有人可以帮帮我吗? 这个问题困扰了我好几天。 请帮帮我,谢谢!
我遇到了与PyCharm 2018.1 + Python 3.6.2相同的问题。
这条线是关键:
LINK : fatal error LNK1104: cannot open file 'C:\Users\hp\.pyxbld\lib.win32-2.7\gensim\models\word2vec_inner.pyd'
此错误消息具有误导性。 使用Python,此错误实际上意味着:
cannot open file to write to it
。 某个进程可能会锁定该文件以进行写入,因此链接器无法完成其工作。
以前的Python行import word2vec_inner
锁定写入文件。 重置Python控制台以删除锁:
使用Process Explorer找出锁定文件的程序。 使用Ctrl-F,然后键入有问题的锁定文件的名称,它将为您提供锁定文件的进程。
退出Pycharm,然后在命令行上将Cython文件预编译到一个包中 。 如果此链接发生更改,则此处为镜像:
想象一下hello.pyx文件中的一个简单的“hello world”脚本:
def say_hello_to(name): print("Hello %s!" % name)
以下可能是相应的setup.py脚本:
from distutils.core import setup from Cython.Build import cythonize setup( name = 'Hello world app', ext_modules = cythonize("hello.pyx"), )
要构建,运行
python setup.py build_ext --inplace
。 然后只需启动一个Python会话,然后从hello import say_hello_to执行,并根据需要使用导入的函数。如果您使用setuptools而不是distutils,则需要注意一点,运行python setup.py install时的默认操作是创建一个压缩的egg文件,当您尝试从依赖包中使用它们时,该文件无法与cimport一起使用。 要防止这种情况,请在setup()的参数中包含zip_safe = False。
