requirements.txt

问题 I have a repository with an inflated requirements.tx that I'd like to clean up. Using pipreqs I've set my requirements.txt to be a minimal set of packages need for my repository. To test this, I setup a virtualenv to install the packages and then run all my unit tests to make sure they're satisfactory. virtualenv temp_venv --no-site-packages source temp_venv/bin/activate pip install -r requirements.txt Which runs fine, but I see that a whole bunch of extra packages are collected and installed

问题 Torch documentation says use pip install torch==1.4.0+cpu torchvision==0.5.0+cpu -f https://download.pytorch.org/whl/torch_stable.html to install the latest version of PyTorch. This works when I do it manually but when I add it to req.txt and do pip install -r req.txt , it fails and says ERROR: No matching distribution . Edit: adding the whole line from req.txt and error here. torch==1.4.0+cpu -f https://download.pytorch.org/whl/torch_stable.html torchvision==0.5.0+cpu -f https://download

问题 I am trying to deploy a Python3.7 Google Cloud Function using the "madmom" python pip package, however specifying madmom==0.16.1 in requirements.txt causes a deployment failure.

问题 I use pip freeze > requirements.txt to gather all packages I installed. But after developing many days, some packages are now unused. How can I find these unused packages and remove them, to make my project more clear? 回答1: Inside Pycharm Go to code > inspect code Select Whole project option and click OK. In inspection results panel locate Package requirements section under Python (note that this section will be showed only if there is any requirements.txt or setup.py file). The section will

问题 This is my first experience deploying a Flask web app to Azure. I followed this tutorial. The default demo app they have works fine for me. Afterwards, I pushed my Flask app via git. The log shows deployment was successful. However, when I browse the hosted app via link provided in "Application Properties", I get a 500 error as follows: The page cannot be displayed because an internal server error has occurred. Most likely causes: IIS received the request; however, an internal error occurred

问题 Package managers for JavaScript like npm and yarn use a package.json to specify 'top-level' dependencies, and create a lock-file to keep track of the specific versions of all packages (i.e. top-level and sub-level dependencies) that are installed as a result. In addition, the package.json allows us to make a distinction between types of top-level dependencies, such as production and development . For Python , on the other hand, we have pip . I suppose the pip equivalent of a lock -file would
