Installation

Datapane's Python library and CLI can be installed using either conda or pip on macOS, Windows, or Linux.

conda

If you use conda, you can install it with:

$ conda install -c conda-forge datapane

pip

If you use pip, you can install it with:

$ pip3 install -U datapane

Windows Tips and Troubleshooting

We generally recommend installing via conda over pip on Windows as it's easier to install all the required dependencies.

If you need to install Python first, the latest versions of Windows 10 can install Python for you automatically - running python from the command-prompt will take you to the Windows Store where you can download an official version. We also strongly recommend using a 64-bit rather than the 32-bit version of Python, you can check this by running the command python -c "import struct; print(struct.calcsize('P')*8, 'bit')" from the Command Prompt.

python -c "import struct; print(struct.calcsize('P')*8, 'bit')"

Also note that on Windows, you can run the datapane command either by running datapane or datapane.exe on the command-line.

Some specific issues you may encounter on Windows include:

Import errors when running/importing datapane

You may encounter errors such as ImportError: DLL load failed when running datapane or importing it within your Python code.

If so, try installing the Visual C++ Redistributables for Windows from Microsoft and running again (you most likely want to download the version for x64, i.e. vc_redist.x64.exe)

Datapane install errors trying to compile pyarrow using Visual C++

This usually occurs when you are running a 32-bit version of Python and installing via pip. Either try using conda or install a 64-bit version of Python (for example from the Windows Store as mentioned above).

This may also occur when using Windows 7 - we only support directly Windows 10, however, it may be worth trying to install via conda instead, if you are stuck on Windows 7.

'datapane.exe' is not recognized as an internal or external command

This occurs when your Windows %PATH% doesn't include all the Python directories, specifically the Scripts directory.

You may notice during the datapane install messages such as (or similar to):

The script datapane.exe is installed in 'C:\users\<USERNAME>\appdata\local\programs\python\python37\Scripts' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.

To fix this, adjust your %PATH% to include your specific Scripts path as mentioned in the pip warning (see https://datatofish.com/add-python-to-windows-path/ for more detailed instructions). Alternatively, you can try running the datapane client directly, using the command python3.exe -m datapane.client instead.

Authentication

As well as a local Python framework for generating reports, Datapane has a server component which is accessed through the CLI and Python library and requires an authentication token. You can authenticate through either the CLI or the Python library, and all future requests from both the CLI and Python library will automatically be authenticated.

Datapane Public

Datapane Public is hosted on datapane.com and is available as a free, public server which you can use to publish and share reports. The API and CLI are configured to use this server by default. After you sign up for a free account, copy the API key provided in the web interface. Next, login using the CLI or Python library using this key. All future requests from both the CLI and Python library will automatically be authenticated.

$ datapane login 
Enter your API Key: [paste your API key here]

import datapane as dp
dp.login(token=your_token)

Datapane for Teams

Datapane for Teams provides private hosted servers and supports on-premise instances for organizations. In such a case, log in to your instance, for instance https://your-company.datapane.net, using the credentials provided to you by your admin.

Similarly to using the public instance, your home page will indicate your API key and you will be able to authenticate by passing in your API key to the login command. You will need to pass in the full URL of your server (including the https://) to the login command as follows.

$ datapane login --server=https://[your-server].datapane.net
Enter your API Key: [paste your API key here]

import datapane as dp
dp.login(token=your_token, server='https://[your-server].datapane.net')

$ datapane --env public login
$ datapane --env acme login --server=https://acme.datapane.net

Check your Authentication

To check you have access and which account you are logged in as, run:

$ datapane ping

import datapane as dp
dp.ping()
