How fix this error: returned non-zero exit status 1 in Mallet?

Please help me with the following error. I tried a lot to fix it but with no help. The code:

MALLET_PATH = './Mallet/bin/mallet'



def topic_model_coherence_generator(corpus, texts, dictionary, start_topic_count=2, end_topic_count=10, step=1,cpus=1):
    models = []
    coherence_scores = []
    for topic_nums in tqdm(range(start_topic_count, end_topic_count + 1, step)):
        mallet_lda_model = gensim.models.wrappers.LdaMallet(mallet_path=MALLET_PATH, corpus=corpus, num_topics=topic_nums, id2word=dictionary, iterations=500, workers=cpus)

        cv_coherence_model_mallet_lda = gensim.models.CoherenceModel(model=mallet_lda_model, corpus=corpus, texts=texts, dictionary=dictionary, coherence='c_v')
        coherence_score = cv_coherence_model_mallet_lda.get_coherence()
        coherence_scores.append(coherence_score)
        models.append(mallet_lda_model)
    return models, coherence_scores

lda_models, coherence_scores = topic_model_coherence_generator(corpus=bow_corpus, texts=norm_corpus_bigrams, dictionary=dictionary, start_topic_count=2, end_topic_count=30, step=1, cpus=16)

The error:

0%|          | 0/29 [00:00<?, ?it/s]'.' is not recognized as an internal or external command,
operable program or batch file.
subprocess.CalledProcessError: Command './Mallet/bin/mallet import-file --preserve-case --keep-sequence --remove-stopwords --token-regex "\S+" --input C:\Users\yaiza\AppData\Local\Temp\b44add_corpus.txt --output C:\Users\yaiza\AppData\Local\Temp\b44add_corpus.mallet' returned non-zero exit status 1.

If I write MALLET_PATH = 'C:/Program files/Mallet/bin/mallet' or 'MALLET_PATH = 'rC:/Program files/Mallet/bin/mallet', return the same error but in first sentence changes to

0%|          | 0/29 [00:00<?, ?it/s]'C:/Program files' is not recognized as an internal or external command,
operable program or batch file..

Thank you

Make sure you installed the Java Developers Kit (JDK).

After installing the JDK & restarting your computer for changes to take effect, the following codes for the LDA Mallet worked like charm!

import os
from gensim.models.wrappers import LdaMallet

os.environ.update({'MALLET_HOME':r'C:/mallet/mallet-2.0.8/'})
mallet_path = r'C:/mallet/mallet-2.0.8/bin/mallet.bat'

lda_mallet = LdaMallet(
        mallet_path,
        corpus = corpus_bow,
        num_topics = n_topics,
        id2word = dct,
    )
