问题 I'm still learning how to use Anaconda package manager. I'm trying to install PyKalman through Conda. Conda seems happy to do so but then tries to downgrade all my packages to Python 3.5 from Python 3.6. For example: pandas: 0.22.0-py36h6538335_0 --> 0.22.0-py35_0 conda-forge I'll need 3.6 for later packages I need to install (i.e. blpapi). Is there a good workaround here? 来源： https://stackoverflow.com/questions/49615395/conda-install-of-pykalman-package-reverting-python-to-version-3-5

问题 I do notice there are some similar question asked by different people about why python couldn't locate the packages that are installed using conda install command in their conda environment. Take pyqt for example. 1 I create conda environment: conda create -n myenv python=2.7 pip 2 Activate environment: source activate myenv 3 install packages: conda install pyqt 4 run python: python import pyqt Error report: ImportError: No module named pyqt 5 check out packages installed: pip list doesn't

问题 I'm new to python and the virtual environment stuff. I'm facing issues opening jupyter notebook and Spyder after updating conda. Here are some info about the versions I have: $ conda info active environment : None '''is it caused by this ?

问题 Not sure what the issue is... ...but many of the classifiers will not work on my machine now. I just installed version 14.1 of scikit-learn. Could this be a path thing? Traceback (most recent call last): File "hashtag.py", line 19, in <module> from sklearn.linear_model import SGDClassifier File "C:\Anaconda\lib\site-packages\scikit_learn-0.14.1-py2.7-win-amd64.egg\sk learn\linear_model\__init__.py", line 24, in <module> from .logistic import LogisticRegression File "C:\Anaconda\lib\site

问题 I managed to install on my conda the plotly package with: conda install -c plotly plotly And the matplotlib with: conda create --name mpl33 python=3.3 matplotlib ipython-notebook But I cant create one env with both of them inside because the plotly uses python 2.7 and matplotlib python 3.3 Thanks for the help! 回答1: Installation If you create a new environment, I would recommend using a new python version. Currently, I'd use python 3.6, because matplotlib does not support python 3.3 anymore.

问题 I am finding that when I create a Conda environment source activate environment and then deactivate that environment source deactivate environment , my native bash commands no longer work. I've attached an image of ls working before enabling an environment and then not afterwards. I assume that this is something because of my PATH - but I am a novice and am not sure specifically what to fix. I am doing this in Git Bash on Windows. Anaconda 3 and Python 3.5. Please work ls, come on 回答1: Most

问题 I have a python 3 virtual environment managed by conda on Windows. I want to install the mayavi package via conda install mayavi but it says it requires python 2.7. 回答1: Have your luck with a mayavi package available on other channels, by searching on the Anaconda website. As of today, the one maintained on the conda-forge channel is compatible with python 3.5 and 3.6. To install it, conda install -c conda-forge mayavi If mayavi fails with an ImportError: Could not import backend for traits

问题 My ultimate goal is to get python package graph_tool working on my system and also on ipynb if possible. I have already brew install graph-tool , as indicated here, but that's still insufficient. So I follow Anaconda instructions here, and I make decent progress, until the CGAL Library could not be found. Note: to comply with the Anaconda instructions, I installed anaconda3 and created a new conda environment (named py36env ) to conda install all the required packages (packages that must also

问题 I’m trying to run the code below to create a virtual Python environment from a YAML file. I’m running the code in the command line on Ubuntu server. The virtual environment is named py36. When I run the code below, I get the message below. The environment also doesn’t get created. Is this problem caused because I have several packages that I had to install using pip instead of Anaconda? Does anyone know how to solve this issue? I created the YAML file following the example from: https:/
