Issue with Pip install

[hvu89]

I am using Mac OSX Intel with Anaconda Python 3.9.6. When i try to install with pip install arch, this is the error I get.

(base) hvu@hvu22145 ~ % pip install arch WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1129)'))': /simple/arch/ WARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1129)'))': /simple/arch/ WARNING: Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1129)'))': /simple/arch/ WARNING: Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1129)'))': /simple/arch/ WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1129)'))': /simple/arch/ Could not fetch URL https://pypi.org/simple/arch/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/arch/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1129)'))) - skipping ERROR: Could not find a version that satisfies the requirement arch (from versions: none) ERROR: No matching distribution found for arch

I've also tried to install from github with the following errors.

You are having problems connecting to PyPI. If you want you can install all of the requirements directly, and then install from github using

python -m  pip install git+https://github.com/bashtage/arch.git --no-build-isolation

In terms of requirements, you should have

setuptools>=61
wheel
setuptools_scm[toml]>=7,<8
oldest-supported-numpy
Cython>=0.29.24

Happy to answer more questions, but closing since it isn't really anything I can fix.

For anyone with this issue, i was able to resolve it by running this.

pip install --user --trusted-host files.pythonhosted.org --trusted-host pypi.org --trusted-host pypi.python.org --upgrade pip arch
