Now that you know a little about me, let me tell you about the issue I am having:

Getting this error on running the install command conda install -c ml4t zipline-reloaded:

Could not solve for environment specs The following packages are incompatible ├─ pin-1 is installable with the potential options │ ├─ pin-1 1 would require │ │ └─ python 3.11. , which can be installed; │ └─ pin-1 1 would require │ └─ python 3.11. , which can be installed; └─ zipline-reloaded is not installable because there are no viable options ├─ zipline-reloaded [2.0.0.post1|2.0.0rc4|2.1.1|2.2.0|2.3] would require │ └─ python >=3.8,<3.9.0a0 , which conflicts with any installable versions previously reported; ├─ zipline-reloaded [2.0.0.post1|2.0.0rc4|2.1.1|2.2.0|2.3] would require │ └─ python >=3.7,<3.8.0a0 , which conflicts with any installable versions previously reported; └─ zipline-reloaded [2.4|3.0|3.0.3] conflicts with any installable versions previously reported.

Which is weird as python is installed. I have activated environment too. Any help would be greatly appreciated!

Sincerely, A hopeful Zipliner🤞

Managed to workaround it with: conda create -n env_zipline python=3.10 conda install -c conda-forge zipline-reloaded=3.0.3=py310hc1335a1_0

RiseT commented 8 months ago

Try this, which should be the standard way of installing zipline-reloaded:

conda create -n env_zipline
conda activate env_zipline
conda install -c conda-forge zipline-reloaded

Python 3.11 currently only seems to work with a pip install (without conda) of zipline-reloaded (never tried it, though). See https://github.com/stefan-jansen/zipline-reloaded/issues/214
